Full textSince July 2008, a wide rnage of halogenated flame retardants was withdrawed from the market for environmental problems by the European Union. The phosphorous products turn out to be promising candidates. Within the framework of my thesis, the synthesis of allyl cyclic phosphonated monomers is described as well as their telomerization, polymerization and copolymerization in solution using a radical process). Their flame retardant behavior was also evaluated. Allyl cyclic phosphonated monomers are synthesized by transesterification between a glycol with a double bond and hydrogenophosphonate. An NMR study of the obtained diastereoisomers allowed us to fully understand the structure of these compounds. Radical homopolymerization of hydrogenated dioxaphosphorinane, in the presence of AIBN as initiator, allowed us to obtain polymers with two molar mass distributions: one for oligomers and one for polymers of higher molar mass. This second species is due to a hyperbranched structure showing poor solubility in common solvents, which damage the future applications. The telomerization of the same monomer was carried out using dimethyl hydrogenophosphonate as chain transfer agent leading only one population of oligomers. Furtehrmore, the replacement of the hydrogen linked to phosphorus by an alkyl or aryl group simplify the mechanism of polymerization since only linear oligomers are obtained. Acceptor-donor copolymerization of maleic anhydride and phosphonated allyl ethers, allowed producing alternated copolymers with the opportunity to introduce different reactive groups such as carboxylic acids. Then, oligomers were produced by radical polymerization of phosphonated allyl amine in order to potentially use the nitrogen-phosphorus synergy. An overview of all the phosphonated polymers previously synthesized, was done with the aim of testing their flame retardant performances. Thermogravimetric analysis showed a good thermal behavior of the telomers and the copolymers, similar heat release rate was observed by microcalorimeter compare to commercial product. High efficiency of these phosphorus-containing flame retardants polymers was finally evidenced by using the cone calorimeter on textile

Full textStar polymers have attracted considerable attention because of their unique thermal and mechanical properties. At the same time, as sustainable chemistry field is growing in impact at an unprecedented rate, we propose in this work to implement a greener pathway for the synthesis of star D-sorbitol-poly(ε-caprolactone) (star PCL-OHx) using clean solvents (polymerisation in the bulk or in supercritical CO2) and either FDA-approved Sn(Oct)2 catalyst or enzyme catalyst (Novozym® 435). The influence of these parameters on the star architecture (number of arms, MW of arms etc.) was rigorously analysed and corroborated with various analytical techniques (1H NMR, SEC-MALS, SEC-UC, phosphitylation quantitative 31P NMR approach). Linear monohydroxy PCL-OH and dihydroxy telechelic OH-PCL-OH samples were also prepared. The PCL materials obtained were used as hydrophobic macroinitiators for the polymerisation of cyclic hydrophilic ethylene ethyl phosphonate monomer for the synthesis of a range of different amphiphilic materials (i.e. star diblock, linear diblock and triblock copolymers). Self-assembly behaviour in aqueous solution of these copolymers was investigated by DLS, TEM and cryo-TEM. Triblock and star amphiphilic copolymers were revealed to be able to reduce the surface tension (γ) of water down to 45 mN m-1. Finally, enzyme catalysed star PCL-OHx polymers were functionalised with carboxylic end-groups using maleic anhydride. Water-dispersible surface-active ionic star polymers were then obtained. These maleate-functionalised star polymers were then photopolymerised with a small amount of tri(ethylene glycol) divinyl ether (~9wt% of total composition). The UV-cured crosslinked star PCL films produced were then analysed by FTIR, DSC and TGA

Full textThis work presents an unusual approach to prepare a new flame retarded PA6 containing phosphorylated silica formed in situ during extrusion process. This nanocomposite is based on sol-gel method without solvent through reactive processing. A first fundamental point was to evaluate the kinetics and the structure of the inorganic species by carrying out these sol-gel reactions in a model medium of PA6 which is N-methyl acetamide. Thus, it was evidenced that the amide medium is advantageous to perform these reactions. Then, the phosphorus alcoxysilane derivative, the diethylphosphato-ethyltriethoxysilane (SiP) is incorporated in molten PA6. The physical and chemical characterizations of the materials elaborated by reactive extrusion showed the formation of phosphorylated particles in the polymer matrix. Finally the fire retardant properties were evaluated and it reveals that the heat release rate was diminished by more than 50% with only 2w% of phosphorus compared to the pure PA6. This was explained by the formation of a carbonaceous char preventing the heat and the combustion products to diffuse

Full textNew lamellar hybrid materials, potentially usable in thermoelectric applications at room temperature, were synthesized from substituted phosphonic acids and were characterised. The intercalation of conductive polymers was also tested. The hybrid materials were synthesized by hydrothermal process by mixing a zinc or a cobalt inorganic salt and an organic molecule made of a thiophene aromatic ring with a phosphonic acid function grafted in position 2 or 3: 2-thienylphosphonic acid or 3-thiernylphosphonic acid. X-Ray diffraction on single crystal allowed the determination of the lamellar structure of these compounds. It is composed of alternating organic and inorganic layers. For the compounds obtained with the 2 thienylphosphonic acid, incommensurate structures were obtained. The compounds did not present any intrinsic electrical conductivity. Therefore, to induce the electrical conductivity within the organic layer, two strategies were chosen: i) the intercalation of pyrrole or thiophene monomers in the organic layer followed by an in-situ polymerization in order to obtain a conductive polymer; ii) the direct in-situ polymerization of the thiophene involved in the organic layer of the material to form a conductive polymer

Full textThe aim of this work is the synthesis of new vinyl ethers monomers bearing phosphonate groups, in order to study their efficiency as flame retardants. Phosphorus products are known to be a good alternative to halogenated flame retardants, which are involved in environmental problems. Initially, the synthesis of phosphonated vinyl ethers was performed by trans-etherification of ethylvinyl ether in the presence of phosphonated alcohols. Then, the radical copolymerization (A/D) was used to prepare copolymers based on phosphonated vinyl ether and various electron-accepting monomers. Kinetic studies by real-time Infrared and several methods of analyzes were used to characterize these copolymers. In a second step, the radical photocopolymerization of 2-dimethylvinyloxyethylphosphonate was led with a series of electron-accepting monomers, for instance maleimides which form strong complexes with vinyl ethers. The cationic photopolymerization of these phosphonated vinyl ethers is also possible and affords better results than radical photopolymerization. An assessment of all phosphonated polymers was performed in order to test their performances as flame retardants. Thermogravimetric and microcalorimetric characterizations showed good amount of released residues showing that these copolymers are good candidates as flame retardants

Full textThis work deals with the synthesis, the photopolymerization and the adhesive properties of new acidic monomers for dental applications. In self-etch adhesive field: In order to improve self-etch adhesives (SEA) stability, durability and adhesive properties, novel hydrolytically stable phosphonic, difluoromethylphosphonic and bisphosphonic acids have been synthesized. The influence of various parameters (length of the spacer group, nature of the acidic group, and polymerizable extremity etc…) on dentin and enamel adhesion and on stability has been developped. Their photopolymerization with the N, N’ -diéthyl-1,3-bisacrylamidopropane (DEBAAP) has been highlighted. The impact of the acidic function on adhesive properties and chelation to hydroxyapatite has been studied via solid NMR, XPS or ICP-AES. Some of the SEA we have formulated are more efficient than the commercial ones. In self-adhesive cements field: Novel methacrylates bearing phosphonic acid functions have been prepared. Their incorporation in various proportions to a bisGMA/TEGDMA mixture has been studied. The copolymerization of these formulations has been studied by photo-DSC. Incorporation of these monomers results in an inhibition of the mixture polymerization due to the phosphonic function. Then the setup of a new self-adhesive cements has been successfully described

Full textThe aim of this work is to elaborate original lamellar hybrid materials and disperse them in a polymer matrix to obtain nanocomposites. They have been prepared using two different matrixes, one apolar (polyethylene) and one polar (polyamide-12). The two lamellar hybrid systems have been dispersed in these matrixes and studied as part of the hybrid nature. The first one, the lamellar oxide KTiNbO5, has been chemically modified with alkylamines having different carbon chain lengths in order to be compatible with the different polymer matrixes. The dispersion of such materials has allowed improving several properties like thermal stability, mechanical resistance and fire resistance. The second family studied is the copper alkylphosphonate one. They have been prepared with different alkyl chain lengths. The aim of this study is to prepare a hybrid material with a transition metal and to disperse it in the polymer matrixes. A deep structural study of the homologue series has revealed two types of compounds: hydrated for the short alkyl chains (number of carbon atoms≤10) and dehydrated for the alkyl chains with n≥10. These two structural types have shown different magnetic behaviours. Finally, the incorporation of these fillers in polyethylene and polyamide-12 has revealed that the chemical nature of the bond which links the organic part to the inorganic one of the hybrid does not allow obtaining an efficient exfoliation mechanism

Full textA family of porphyrins bearing the meso-diethoxyphosphoryl group directly attached to the porphyrin macrocycle was prepared in fairly good yields (55-70%) according the Pd-catalyzed coupling of 10-bromo-5,15-diarylporphyrins with diethyl phosphite. Experimental procedures for their complexation with different metal ions (Zn(II), Mg(II), Ni(II), Cu(II), Pd(II), Ru(II), Pt(II), Ga(III), In(III), Mn(III), Sn(IV)) have been developed. Next, their selective hydrolysis into meso-porphyrinylphosphonic acids or their monoesters has been investigated. Saponification of the diesters proceeds selectively in THF/MeOH mixture at 60 °C affording corresponding monoesters in high yields. To prepare porphyrinylphosphonic acids, the most convenient route is a two-step, one-pot procedure involving the treatment of porphyrins with TMSBr followed by addition of MeOH.The structures of seven complexes were characterized by single-crystal X-ray diffraction. In the solid state, both alkyl and dialkyl porphyrinylphosphonates form supramolecular assemblies through the axial coordination of the phosphoryl oxygen atom of one porphyrin molecule to the metal center of adjacent molecule. The influence of the nature of metal ions and substituents at the tetrapyrrolic macrocycles on the crystal organization was explored and several unusual biomimetic supramolecular systems were obtained. Structural studies of self-assemblies in solution by means of NMR spectroscopy revealed that Sn(IV) complexes with monoester of meso-porphyrinylphosphonic acids form stable dimeric species through M…OP(O)(OEt) binding of two laterally shifted porphyrin molecules.Next, synthetic approaches to hybrid organo-inorganic materials based on porphyrins bearing phosphonate anchoring groups have been investigated. Covalent grafting of Ru(II), Mn(III) and Sn(IV) complexes with porphyrins onto a surface of mesoporous titanium dioxide through phosphonate anchoring group was developed. The catalytic properties of titania-supported Mn(III) porphyrin in the epoxidation of alkenes by molecular oxygen in the presence of isobutiraldehyde was explored. The possibility of catalyst recycling was demonstrated using the oxidation of cyclooctene as a model reaction.Porous molecular hybrid materials based on titanium dioxide and 5,10,15,20-tetrakis[p-(diethoxyphosphoryl)phenyl]porphyrins have been also prepared by the sol-gel process in organic solvents. The hybrid material based on the metal free porphyrin change the colour in air due to the protonation of the tetrapyrrolic macrocycle by the traces of water

In this thesis, two types of ligands, benzene-1,3,5-trismethylenephosphonic acid (H6btmp) and benzene-1,2,4,5- tetrakismethylenetetraphosphonic acid (H8tmpb), were used to synthesize coordination polymers with transition-metal and lanthanide ions under hydrothermal conditions. The reaction of CuCl2˙2H2O with H6btmp under hydrothermal conditions produced a 3D framework {[Cu3(btmp)(H2O)4]˙H2O}n (1). The reaction of Ln(NO3)3˙6H2O (Ln = Ce, Pr, Nd, Sm) with H6btmp in water produced four 2D frameworks of [Ln(H3btmp)(H2O)3]n [Ln = Ce (2), Pr (3), Nd (4), Sm (5)]. Compound 1 was prepared under weak acid (pH = 4-5) condition, while compounds 2-4 synthesized under strong acid environment. The self-assembly of Ce(NO3)3˙6H2O with H8tmpb in water produced a 2D framework {[Ce4(H4tmpb)3(H2O)6]˙19H2O}n (6). Reaction of Ln(NO3)3˙6H2O (Ln = Sm, Eu, Gd, Tb, Dy) with H8tmpb in water produced five 2D frameworks with a general formula {[Ln2(H2tmpb)(H2O)8]˙2H2O}n [Ln = Sm (7), Eu (8), Gd (9), Tb (10), Dy (11)]. The reaction of Er(NO3)3˙6H2O with H8tmpb in water afforded a 2D framework {[Er2(H5tmpb)2]˙6H2O}n (12). The structures of these coordination polymers (1-12) were characterized by IR spectroscopy, elemental analysis and single-crystal or powder X-ray diffraction methods. The thermal stability properties of the products were studied by TGA and the magnetic susceptibility were also examined.

The first part of this thesis reports on the hydrothermal synthesis a 3D coordination polymer {[Cu2(L1)(2H2O)]•H2O}n (1), a 2D coordination polymer [Co6(L2)2(4H2O)]n (2), and a 3D coordination polymer [Cu4(L2)2(4H2O)]n (3), thesis will discuss the structures, thermal stability and physical properties of the products. The second part will focus on the reaction of alkali ions (NaI, KI, CsI), and alkaline earth ion (MgII) with L2 under room temperature conditions produced a 1D coordination polymer {Na4[Mg(H2O)6]2[Mg2(L2)2(H2O)18]•12H2O} (4), and two discrete structures {K2[Mg(H2O)6]2[Mg3(L2)2(H2O)20]•13H2O}n (5), {Cs4[Mg(H2O)6] 4(L2)2•16H2O} (6). The third part will focus on the reaction of alkali ions (NaI, KI), alkaline earth ion (CaII), transition-metal ions (CoII, NiII) , and lead ion (PbII) with L2 under room temperature conditions produced a 2D coordination polymer {K6[Ni(H2O)6][Ni2(L2)2(H2O)25]•2H2O}n (7)、 {K4[Ca4(L2)2(H2O)24]•6H2O}n (8), and a 1D coordination polymer {[Pb4(L2)2(H2O)4]•6H2O}n (9), and a discrete structure {Na5[Co(H2O)6]2(L2)2(H2O)14•0.5C2H2O4} (10). The fourth part of Ion-exchange studies, by treating 4 in water or an aqueous solution of Transition-metal nitrate (Co(NO3)2.6H2O and Ni(NO3)2.6H2O), revealed that a surprisingly dissolution/reassembly process occurred, leading to the rearrangement of metal-phosphonate building blocks and the formation of new metal-phosphonate species (11∼13). The structural transformations were confirmed by single-crystal and powder X-ray diffraction (PXRD) data.
