Full textENGLISH ABSTRACT: Finding use for byproducts from the chemical industry holds many advantages for a country's economy. Synthesis of new monomers from such byproducts adds value to otherwise otherwise low-value material. The synthesis of a new olefin-modified acrylate monomer, 1-methyl-1-propyl-hexyl acrylate (1-MPHA), derived from 1-pentene, is reported. Homopolymerisation of the monomer 1-MPHA was carried out in both benzene and in toluene. The products of full-conversion of the homopolymer poly-(1-MPHA) were characterised by GPC, NMR, TGA and DMA. Kinetic studies of the homopolymerisation process of 1- MPHAwere also undertaken. The monomer 1-methyl-1-propyl-hexyl acrylate (1-MPHA) was copolymerised with methyl methacrylate (MMA). Samples obtained from full conversion copolymerisations at various 1-MPHAIMMAfeed ratios were characterised by GPC, NMR, TGA and DMA. Reactivity ratios of the two monomers were obtained from in situ 1H NMR kinetic studies. 1-MPHA was also copolymerised with vinyl acetate (VAc). Samples obtained from full conversion copolymerisation with a 1-MPHA content ranging from 2 to 16 wt% were characterised by GPC, NMR, TGA and DMA. The solubility parameter and the hydrophobicity of the VAc/1-MPHA copolymers were also determined. Reactivity ratios of the two monomers were obtained from in situ 1HNMR kinetic studies. Further copolymerisation studies with styrene and glycidyl methacrylate as comonomers were undertaken. The chemical analysis and thermogravimetric analysis of the copolymers are reported. In conclusion, the use of 1-methyl-1-propyl-hexyl acrylate as a comonomer results in a reduction in the glass transition temperature, better thermal stability, increased hydrophobicity with an insignificant loss in stiffness of the copolymers. These properties are due to the long and branched chain structure of the 1-MPHA monomer.
AFRIKAANSE OPSOMMING: Gebruik van byprodukte van die chemiese nywerheid hou groot voordele in vir die land se ekonomie. Sintese van nuwe monomere vanuit sulke byprodukte dra by tot waardetoevoeging tot andersins lae-waarde byprodukte. Die sintese van 'n nuwe olefien-gewysigde akrilaatmonomeer afkomstig van 1-penteen, naamlik 1-metiel-1-propiel-heksielakrilaat (1-MPHA), word hier beskryf. Homopolimerisasie van die monomeer 1-MPHA is uitgevoer in beide benseen en tolueen. Die produkte van die volledige omskakeling van die homopolimeer is met behulp van GPC, KMR, TGA en DMA gekarakteriseer. Die reaksiekinetika van die homopolimerisasie van 1-MPHA is ook ondersoek. Die monomeer 1-MPHA is met metielmetakrilaat (MMA) gekopolimeriseer. Monsters van die volledig omgeskakelde kopolimere met verskeie 1- MPHNMMA voerverhoudings is m.b.v. GPC, KMR,' TGA en DMA gekarakteriseer. Die reaktiwiteitsverhoudings van die twee monomere is vanaf 1HKMR-studies bepaat. 1-MPHA is ook met vinielasetaat (VAc) gekopolimeriseer. Monsters van die produk van die volledige kopolimerisasie met 1-MPHA , met 'n inhoud van 2- 16 massa 0/0, is ook m.b.v. GPC, KMR, TGA en DMA gekarakteriseer. Die 1- MPHA het die hidrofobisiteit van VAc/1-MPHA aansienlik verhoog. Die reaktiwiteitsverhoudings van die twee monomere is vanaf in situ 1H KMRstudies bepaal. Verdere kopolimerisasiestudies met stireen en glisidielmetakrilaat as komonomere is onderneem. Chemiese- en termogravimetriese analises van die kopolimere is gedoen en gerapporteer. Ter afsluiting, die gebruik van 1-metiel-1-propiel-heksielakrilaat as komonomeer het 'n verlaging in die glasoorgangstemperatuur, verhoogde termiesestabiliteit, verhoogde hidrofobisiteit, en 'n klein verlies in die stewigheid (Eng. stiffness) van die kopolimeer tot gevolg. Hierdie eienskappe is as gevolg van die lang, vertakte kettingstruktuur van die 1-MPHA monomeer.

Full textThe aim of this work was to develop 100% solids photo-polymerizable acrylate coatings, intended to protect thermoplastic pieces made of polycarbonate against mechanical damage, in particular scratches. The relationships between the composition, the structure and the properties of these coatings were examined. For this purpose the morphology, the thermomechanical properties and the scratch resistance of the materials, assessed by micro-scratch tests, were studied. The kinetics of the polymer network formation was also studied by photo-DSC experiments. All the materials feature a high elastic modulus and a broad mechanical relaxation in dynamic thermomechanical analysis. A 100% solids petro-based coating (standard) constituted the starting point of this work. First it was compared to a commercial photo-polymerizable coating containing solvents, specially designed to protect thermoplastic pieces. This commercial coating turned out to be more efficient against scratches. In a second time was studied the influence of the percentage of a multicyclic monomer, taking part in the composition of the standard petro-based coating, on the properties of the latter. The modification of its proportion does not bring any advantage concerning the scratch resistance. Silica, alumina and zirconia nanoparticles, dispersed in an acrylate monomer, were then incorporated in the standard petro-based coating. A particular organization of the silica or alumina nanoparticles in the materials could be observed by transmission electron microscopy. A high filler content is required to observe an increase in the elastic modulus and an enhancement of the scratch resistance of the coating (≥15% by weight for the nano-silica). Moreover, no change of the photo-polymerization kinetics was noticed through the addition of 5% by weight of nano-silica in the coating. Finally, some of the petro-based acrylate compounds of the standard coating were substituted by commercially available bio-based acrylate monomers. Both types of coatings feature similar polymerization kinetics. The conclusions concerning the comparison of the scratch resistance of the bio-based and standard petro-based coatings depend on their thickness. The incorporation of a bio-based monoacrylate compound in low thickness coatings tends to improve the elastic recovery. Isobornyl acrylate is particularly interesting since it also tends to delay the apparition of cracks along the scratch

Full textZur Bestimmung von Terminierungsgeschwindigkeitskoeffizienten wurde die Polymerisation durch einen einzelnen Laserpuls initiiert und der Monomer-zu-Polymer-Umsatz anschließend mittels zeitaufgelöster Nahinfrarotspektroskopie verfolgt. Die Zeitauflösung ist auf 0.33 μs verbessert worden. Wiederholte Einstrahlung von Laserpulsen in Kombination mit nahinfrarotspektroskopischer Analyse liefert Terminierungsgeschwindigkeitskoeffizienten als Funktion des Grades des Monomerumsatzes. Untersuchungen der Terminierungskinetik von Prop‑2‑enamid, 2‑Methylprop‑2‑enamid, N,2‑Dimethylprop‑2‑enamid, N,N‑Dimethylprop‑2‑enamid und 1‑Vinylpyrrolidin‑2‑on wurden, aufgrund des besseren Signal-Rausch-Verhältnisses bei hohen Drücken, bei 2 000 bar durchgeführt. Weitere Messungen wurden im Fall der meisten Prop‑2‑enamide bei Drücken von 500 bar, 1 000 bar und 1 500 bar durchgeführt. Die dadurch erhaltenen Aktivierungsvolumina können zur Abschätzung des Terminierungsgeschwindigkeitskoeffizienten bei Umgebungsdruck verwendet werden. Die Aktivierungsvolumina der Terminierungsgeschwindigkeitskoeffizienten von N,2‑Dimethylprop‑2‑enamid und von Prop‑2‑enamid belaufen sich auf 12.4 cm3·mol−1 beziehungsweise 14.3 cm3·mol−1. Das Aktivierungsvolumen im Fall von N,N‑Dimethylprop‑2‑enamid (4.9 cm3·mol−1) ist kleiner als erwartet. Terminierungsgeschwindigkeitskoeffizienten von 1‑Vinylpyrrolidin‑2‑on konnten für einen großen Bereich der Anfangsmonomerkonzentration und des Grades des Monomerumsatzes erhalten werden. Diese Daten ermöglichen eine detaillierte Analyse der Parameter, die zur Beschreibung der Monomerumsatzabhängigkeit des Terminierungsgeschwindigkeitskoeffizienten verwendet werden. Es wird angenommen, dass der Terminierungsgeschwindigkeitskoeffizient innerhalb des untersuchten Monomerumsatzbereichs durch Segment-, Translations- und Reaktionsdiffusion kontrolliert ist.
Im Fall von N,N‑Dimethylprop‑2‑enamid und 1‑Vinylpyrrolidin‑2‑on wurden dynamische Viskositäten von Monomer–Wasser-Gemischen bei Umgebungsdruck bestimmt, um das Verständnis der Terminierungskinetik zu erleichtern. Für diese beiden Monomere wurde durch Pulslaser-induzierte Polymerisation eine große Anzahl von Terminierungsgeschwindigkeitskoeffizienten in Abhängigkeit von der Anfangsmonomerkonzentration erhalten.
Zur Bestimmung des Terminierungsgeschwindigkeitskoeffizienten von Prop‑2‑enamid in Abhängigkeit vom Monomerumsatz wurden chemisch initiierte Polymerisationen bei Umgebungsdruck durchgeführt. Die erhaltenen Werte stimmen gut mit Daten überein, die mit Hilfe von Pulslaser-induzierten Polymerisationen ermittelt wurden.
Untersuchungen der binären Copolymerisation von 1‑Vinylpyrrolidin‑2‑on und Natriumacrylat zeigten einen ausgeprägten Einbau von Natriumacrylat in das gebildete Copolymer. Dies wurde mittels Kernspinresonanzspektroskopie gemessen. Die Monomerreaktivitätsverhältnisse wurden mit Hilfe der Lewis–Mayo-Gleichung bestimmt.

Full textToday, optical quality object fabrication, such as ophtalmic lenses, uses a mould process. Those moulds allow obtaining object named “semi-finished” or “finished” voluntarily oversized. Then, those are cut, machined and shaped in order to fit different eyeglasses corrections, and frames. 90% of the initial material used are wasted, and will be hardly recycled The additive manufacturing processes seem to be a good idea to avoid the waste production. This PhD thesis objective is to develop a new additive manufacturing process to obtain optical quality objects. With the good photopolymerization process, it is possible to manage a continuous polymerization front under an UV light beam. This study was organised into several separated parts. The first one is the study of the formulation, and the chemistry, to control the polymerization front propagation. The second one is the equation modelization of the front propagation, using a well-known equation in the additive manufacturing process field. Finally an applicative part describes the industrial problem starting with the optical quality description of the object, and the knowledge transfer on a semi-industrial irradiation system

Full textThis paper describes the synthesis of a reactive amphiphilic polyurethane, and its use as an emulsifier for the emulsion polymerization of styrene. The colloid properties and the structure of the emulsifier in the aqueous phase have been investigated. When the acrylic polymerization is carried out with hydrophobic monomers, we obtain a composite particle structure. The variation of particle size and particle size distribution as a function of the reaction parameters was measured by light scattering methods and Flow-fieldflow-fractionation (F-FFF) . Through investigation by dilatometry and reaction calorimetry it was possible to compare the polymerization process with that of common emulsion polymerization. Solid State NMR analysis allowed us to develop a core-shell model for the composite particle structure, and to determine the presence of an interphase layer between core and shell. Atomic Force Microscopy (AFM) methods were used to characterize the surface of the films, and tapping mode AFM was used to characterize the polymer phase separation on the micro scale

Full textThe evolution of laws on the use of biocide products makes it necessary to explore innovative methods of treating wood. In this context, the presented research focuses on a new alternative called a "non-biocide" treatment method involving the manufacture of solid wood-polymer composites obtained by impregnation of monomers and in situ polymerization caused by heating. Methyl methacrylate, four organic acrylates and three water-soluble acrylates, and furfuryl alcohol were tested. Composites manufactured were characterized: the polymer is present in the timber and may be resistant to leaching in water. Wood has been densified, while the composites are less hydrophilic and more dimensionally stable; the mechanical properties are improved. Treatment can induce high durability. Otherwise, an innovative method of impregnation was tested: axial impregnation. This process consists in the low-pressure impregnation of green wood ridges by treatment solution transiting via natural pathways of sap circulation. Ridges were impregnated with a copper solution, later determined to ensure good distribution of the product in the timber; this allowed the validation of the axial impregnation method for beech, hornbeam and birch. Finally, the composites were produced by axial impregnation of polymerizable aqueous solutions based on furfuryl alcohol; they are resistant to water leaching and less hydrophilic than the original wood. Their durability in the presence of wood-destroying fungi is improved, particularly in the case of the more concentrated treatment

In this study, the bridging agent, 3-(trimethoxysilyl) propylmethachylate, was treated on the inner wall of a bare capillary prior to the polymerization of acrylate monomers. The polymerization solution, consisting of butyl methacrylate (BMA) as bulk monomer, ethylene dimethacrylate as crosslinker, mono-(2-methacryloyloxy)ethyl succinate (MES) as ionizable monomer, and a mixture of H2O, 1,4-butanediol and 1-propanol as porogenic solvent, was coated on the treated capillary to form a porous-layered open-tubular phases in the electrochromatographic capillary (BMA-MES). Another mixture of BMA and carbon nanotubes (CNTs) was prepared to form the electrochromatographic capillary (BMA-CNT) in a similar manner. The two capillaries were tried to separate nitrogenous bases, nucleosides, flavonoids and phenolic acids. The CEC mechanism of these separations was also studied. Then, in order to understand whether the monomer in polymerization mixture was the essential, BMA was taken off from the polymerization solutions prepared for BMA-MES and BMA-CNT columns. The EOF and the optimun CEC conditions for the completed two columns, MES and MES-CNT, were compared with BMA-MES and BMA-CNT columns, respectively. According to the above results, they will be suitable to analyze the Chinese herbs, such as Acanthopanax senticosus and Lupinus albus Linn.

UV inks have the advantage of low pollution, but they cannot completely replace the advantages of solvent-based and water-based inks. For example: The traditional solvent type ink, water-based ink toughness, elasticity, hardness and heat resistance. This study uses UV-band ultraviolet light to cure different compositions and different compositions of polyurethane acrylic resin. To understand the pros and cons of changes in its physical properties. At a fixed light initiator content of 3g, defoamer 5300, 2g, defoamer 5368, 0.2g, leveling agent 0.5g, the desired test material was obtained by varying the ratio of oligomer to monomer. Difunctional (Aliphatic Difunctional Urethane Acrylate, PU-2100) or Hexafunctional Urethane Acrylate (PU-5000) with acrylics containing monofunctional monomers (2-phenoxyethyl acrylate, R-210) containing monofunctional monomers and acrylic (polydipentaerythritol hexaacrylate, R-265) With the increase and decrease of the proportion of mutual deployment, the finished product was screen printed with 1/200 of the screen mesh, and the ink layer after printing was cured at a speed of 8 meters per minute on a UV light machine to obtain a film of 0.1 MM. The ratios of the elasticity, hardness and Tg points of the films of the mixed resin sheets obtained in the various ratios A and B as shown below were measured by DMA and DSC. A. Contains difunctional or hexafunctional urethane acrylics, The properties of the resin ester change with the type of monomer functional groups, study its elasticity, hardness and Tg point changes. B. To study the change of elasticity, hardness and Tg point of the bifunctional or hexafunctional urethane acrylic resin with mixed monomer functional groups. The research obtained knows that the data is mixed and formulated into UV inks, thereby optimizing the shortcomings of the current UV inks, and can take advantage of the quick-drying, low-pollution, and process-saving advantages of UV inks to replace some of the current traditional inks.

Ferroelectric liquid crystals (FLCs) have great electro-optical properties of fast response time (τ), large spontaneous polarization (Ps) value, high contrast ratio (gray-scale), wide view angle, bistable character, and memory effect. However, the drawbacks of FLC materials such as thin cell gap are impeded the application of display and other uses of electro-optical devices. In this work, we combine the advantages of guest-host system, in situ polymerization, and photoinduced reorientation to improve the drawbacks of FLCs. The monomers containing with acrylate and cinnamste groups were synthesized. The liquid crystal (LC) thermal properties were characterized by differential scanning calorimetry, optical polarizing microscopy, temperature-dependent power X-ray diffraction measurements. The detailed relationships between chemical structures and liquid crystalline behaviors were discussed. In the results, it shows that all of the compounds have LC behaviors, except ACI812N and ACI1012N. As the dipole moment of tails increases, the crystalline point decreases, then widen the range of smectic phase. In the case of two chiral centers, the SC* phase can be achieved about 50℃ (including room temperature). In the guest-host system, photoinduced reorientation can be achieved by ordered cross-type network via irradiated with 313nm linearly polarized ultraviolet light (LP-UV light). The ordered cross-type network can improve the electro-optical properties (higher spontaneous polarization value, constant response time, and higher contrast ratio) of the guest-host system. Furthermore, the cell gape of FLC display can be up to 5μm (potentially larger than 5μm). Upon irradiation, theses mixture-filled 5μm cells exhibit similar electro-optical properties as compared to those in the 2μm cells.
