Résumé :
AbstractAn appropriate approach has been used for the preparation of silica/P(MMA-co-St) hybrid nanoparticles through converting previously prepared inverse miniemulsions into a direct miniemulsion and consequently, using the droplet nucleation polymerization technique. In the early stage of the procedure, silica particles were synthesized from TEOS in the presence of NH4OH or HCl as a catalyst through a base or acid-catalyzed sol-gel process. TEOS, ethanol and tirmethoxyvinylsilan were mixed in MMA:St (50:50) to create the inverse miniemulsion I, similarly CTAB, NH4OH/HCl and distilled water were dispersed into MMA:St (50:50) and called inverse miniemulsion II. Then, the two mentioned inverse miniemulsions were emulsified in water to achieve direct miniemulsion. The nature of the catalyst and TEOS concentration varied, for the aims of investigation, their effect on the morphology and size of hybrid nanoparticles. This route provided a unique process for silica/polymer hybrid nanoparticles production, avoiding organic solvents. Transmission electron microscopy micrographs revealed that, the morphology of the hybrid nanoparticles can be controlled by the nature of the catalyst.

Résumé :
Reversible addition–fragmentation chain transfer (RAFT) polymerization of styrene has been implemented in aqueous miniemulsion based on the in situ surfactant generation approach using oleic acid and potassium hydroxide in the absence of high energy mixing. The best results were obtained using the RAFT agent 3-benzylsulfanyl thiocarbonyl sufanylpropionic acid (BSPAC), most likely as a result of the presence of a carboxylic acid functionality in the RAFT agent that renders it surface active and thus imparts increased colloidal stability. Stable final miniemulsions were obtained with no coagulum with particle diameters less than 200 nm. The results demonstrate that the RAFT miniemulsion polymerization of styrene employing the low energy in situ surfactant method is challenging, but that a system that proceeds predominantly by a miniemulsion mechanism can be achieved under carefully selected conditions.

Résumé :
AbstractThe kinetics of free-radical copolymerization and terpolymerization of acrylamide (AAm), N, N′-methylenebis(acrylamide) (MBA) and methacrylic acid (MA) in the inverse water/monomer/cyclohexane/Tween 85 miniemulsion was investigated. Polymerizable sterically-stable miniemulsions were formulated in cyclohexane as a continuous medium. Polymerizations are very fast and reach the final conversion within several minutes. The dependence of the polymerization rate vs. conversion is described by a curve with two nonstationary rate intervals. The maximum rate of polymerization slightly increases with increasing concentration of crosslinking monomer (MBA) and strongly decreases by the addition of MA. The rate of polymerization is inversely proportional to the 0.9th and 1.8th power of the particle concentration without and with MA, respectively. The number of polymer particles is inversely proportional to the 0.18th and 0.13th power of MBA concentration. The kinetic and colloidal parameters of the miniemulsion polymerization are discussed in terms of microemulsion polymerization model.

Résumé :
Polymerized rosin/polyacrylate composite miniemulsions were prepared by in-situ semi-continuous miniemulsion polymerization method with polymerized rosin as tackifying resin. The effect of polymerized rosin amount on the monomer conversion rate, the water absorption rate, adhesion properties including initial force, 180opeel strength and shear resistance of the composite latex films were studied, and the structure was also characterized by FTIR and DSC. The results showed that polymerized rosin played the role of inhibition and chain transfer agent in the polymerization process. Polymerized rosin was compatible well with polyacrylate. With the introduction of polymerized rosin, the water absorption rate and heat resistance of the composite latex films were not decreased. When polymerized rosin amount was 3%, the initial force, 180opeel strength and shear resistance of the composite latex films were 13 #, 200 N/m and 21 h, respectively.

Texte intégral
Résumé :
The course of the polymerization of vinyl stearate has been followed by dilatometry and by light scattering. Kinetically stable and visually clear or at most opalescent 'miniemulsions' were used to minimize the scattering (otherwise large) by emulsion droplets. Light-scattering results demonstrate that the final particle size of the latexes may be greater or less than that of the emulsion droplets in the starting miniemulsion. This suggests that polymer particles are nucleated from the aqueous (micelle-containing) phase, and grow by transport of vinyl stearate monomer through the aqueous medium from the emulsion droplets to feed polymerization in the particles. Thus the droplets gradually decrease in size and disappear when all the monomer has been taken up by absorption into micelles or into growing particles. A previously proposed droplet-particle collision theory does not appear to be necessary.

Résumé :
An alternative approach for the synthesis of styrene butadiene rubber (SBR) copolymer latexes was explored in order to obtain low gel fractions and high solid contents. The ultra-turrax-assisted miniemulsion stabilized by in situ surfactant generation was adopted as the main strategy since this technique can inhibit the eventual presence of secondary nucleation producing polybutadiene particles and also control the cross-linking degree. Styrene monomer was first miniemulsified using an ultra-turrax and in situ generated surfactant using either hexadecane (HD) or octadecyl acrylate (ODA) as the hydrophobe. Dynamic light scattering (DLS) measurements of droplet size indicated faster stabilization and the production of smaller droplet diameters ca. 190 nm (PdI = 0.08) when employing in situ generated potassium oleate (K-Oleate) in comparison to SDS-based miniemulsions. High butadiene-level SBR latexes with ca. 50% solids content, a glass transition temperature (Tg) of −52 °C, and a butadiene to styrene weight ratio of 75:25, were then obtained using the miniemulsion droplets as seeds. Turbiscan and DLS measurements revealed a very stable resulting latex with SBR particle diameter of ca. 220 nm and a low polydispersity index (PdI). Secondary nucleation was prevented as indicated by the low Np/Nd value. Cryo-TEM images showed a narrow distribution of particle size as well as the absence of agglomeration. The gel content was below 10% when tert-dodecyl mercaptan (t-DM) was used as chain transfer agent (CTA).

Résumé :
An innovative enzymatic polycondensation of dicarboxylic acids and dialcohols in aqueous polymerization media using free and immobilized lipases was developed. Various parameters (type of lipases, temperature, pH, stirring type and rate, and monomer carbon chain length) of the polycondensation in an oil-in-water (o/w) miniemulsion (>80% in water) were evaluated. The best results for polycondensation were achieved with an equimolar monomer concentration (0.5 M) of octanedioic acid and 1,8-octanediol in the miniemulsion and water, both at initial pH 5.0 with immobilized Pseudozyma antarctica lipase B (PBLI). The synthesized poly(octamethylene suberate) (POS) in the miniemulsion is characterized by a molecular weight of 7800 g mol−1 and a conversion of 98% at 45 °C after 48 h of polycondensation in batch operation mode. A comparative study of polycondensation using different operation modes (batch and fed-batch), stirring type, and biocatalyst reutilization in the miniemulsion, water, and an organic solvent (cyclohexane:tetrahydrofuran 5:1 v/v) was performed. Regarding the polymer molecular weight and conversion (%), batch operation mode was more appropriate for the synthesis of POS in the miniemulsion and water, and fed-batch operation mode showed better results for polycondensation in the organic solvent. The miniemulsion and water used as polymerization media showed promising potential for enzymatic polycondensation since they presented no enzyme inhibition for high monomer concentrations and excellent POS synthesis reproducibility. The PBLI biocatalyst presented high reutilization capability over seven cycles (conversion > 90%) and high stability equivalent to 72 h at 60 °C on polycondensation in the miniemulsion and water. The benefits of polycondensation in aqueous media using an o/w miniemulsion or water are the origin of the new concept strategy of the green process with a green product that constitutes the core of the new greener polymer-5B technology.

Purpose The purpose of this study is to prepare nanoscale copolymer-silicon dioxide (SiO2) dispersion for formulating textile printing white ink. Design/methodology/approach Nanoscale copolymer-SiO2 dispersion was prepared via miniemulsion polymerization. The miniemulsion formulation was optimized for preparing stable SiO2/O/W miniemulsion and nanoscale copolymer-SiO2 dispersion. The nanoscale copolymer-SiO2 was investigated by transmission electron microscope (TEM), X-ray diffraction (XRD), differential thermal gravity (DTG) and thermogravimetric analysis (TGA). The performance of white inks from this colorant was further investigated. Findings Nanoscale copolymer-SiO2 had a core-shell structure with about 45 nm encapsulated copolymer layer when it was synthesized under optimal miniemulsion formulation 60 per cent mass ratio of styrene (St) to KH570-SiO2, 5.0 per cent hexadecane to St and 2.0 per cent concentration of DNS-86. The nanoscale copolymer-SiO2 white ink had high thermal and centrifugal stability with high purity and color fastness. Research limitations/implications The miniemulsion polymerization conditions required a careful control before favorable results could be achieved. Practical implications The nanoscale copolymer-SiO2 dispersion and white ink prepared by this method showed excellent stability. This research could accelerate the textiles inkjet printing application. Originality/value The reactive stabilizer DNS-86 is innovatively introduced into the miniemulsion polymerization to improve the stability of the nanoscale copolymer-SiO2 dispersion. The white ink was formulated from nanoscale copolymer-SiO2 to improve the fastness of the printed fabrics.

Résumé :
This work presents a simple and facile strategy for the creation of Prussian blue containing polymeric nanocapsules. An crosslinked inverse miniemulsion with a formula of water/ K4Fe(CN)6/1,2-bis-(-2-iodoethyl) ethane(BIEE)/ toluene/ PDMAEMA-b-PS stabilizer mixture was prepared as soft template firstly. A crosslinking nanocapsule structure with K4Fe(CN)6 in water core could be achieved by a crosslinking reaction between PDMAEMA-b-PS stabilizers and BIEE. Upon the following addition of FeCl3 ether solution into the oil phase of this inverse miniemulsion, a coordination reaction between two iron salts occurred immediately to form a Prussian blue complex. Due to the solubility limitation of FeCl3 in the oil phase of the miniemulsion, forcing the coordination reaction of K4Fe(CN)6 and FeCl3 mainly occurred at the oil-water interface of the nanocapsules, resulting in a soft polymer/Prussian blue(PB) hybrid nanocapsule.

Résumé :
Miniemulsion polymerization process is a very versatile technique used for the polymeric encapsulation of the many essential oils. In this process some surfactant compounds are used to define the capsules characteristics, as an example the Sodium Lauryl Sulphate (SLS) that is one of the most used surfactants. But, after the miniemulsion polymerization synthesis the residual amount of SLS can manifest an antimicrobial action that can improve or to prejudice the final properties of the encapsulated products, depending of its percentual concentrations. In this sense, the objective of this work was to evaluate the antimicrobial activity of polycaprolactone (PCL) capsules synthesized with different residual concentrations of the SLS surfactant after the miniemulsion polymerization processes. The antimicrobial evaluations demonstrated from solid media diffusion test that the PCL microcapsules are microbiologically inactive for the bacteria Staphylococcus aureus and Escherichia coli when are synthetized with residual concentrations of SLS below 0.0125%. The minimum inhibitory concentration (MIC) of residual SLS for the bacteria Staphylococcus aureus is 0.0146% and for the bacteria Escherichia coli the complete bacterial inhibition not was detected at the maximum residual concentration studied of 0.1167%.

The PS-Nag nanocomposites synthesized via miniemulsion polymerization were made at two different concentrations of the initiator (0.7 and 2.5 g/L in H2O); at higher concentration of the initiator the conversion and efficiency of encapsulation increases, and the average particle size decreases. The PS-NAg composites showed excellent antimicrobial performance toward bacteria such as Escherichia coli and Staphylococcus aureus.

Polyurethane prepolymer capped by vinyl group (PUV) was synthesized by reaction of hydroxyethyl methacrylate and toluene diisocyanate using di-n-butyltin dilaurate as catalyst, and then polyurethane-poly(butyl acrylate) hybrid latexes were prepared via miniemulsion polymerization of PUV and butyl acrylate (BA). Fourier transform infrared, differential scanning calorimeter were adapted to characterize the structure of PUV and PU-PBA and the properties of their films. The results show that the decrease of BA/PUV ratio result in an increase of the hardness and glass transition (Tg) of PU-PBA, but reduce the stability of miniemulsion and elasticity of final copolymer films.
