This work is an attempt to provide antistatic properties to a commercial epoxy resin made up with Epikote 1001(R) and Euredur 423(R). In this aim, two compounds were selected which could be chemically bonded to the resin network: (2,3-epoxypropyl)trimethylammonium chloride which contains an epoxy group and the ammonium chloride group for the antistatic properties and also tetrabutylammonium 2-aminoethanesulfonate which contains an amino group and the tetrabutylammonium sulfonate group. Different formulations of the resin were prepared with both compounds, their viscosity and their resistivity were measured. Antistatic properties were obtained with the highest contents of epoxy compound. On the contrary no antistatic properties could be observed with the amino compound. Hardness and adherence tests have given suitable results for the antistatic formulations.
Copolymers bearing benzodithioate quaternary ammonium salts moieties are synthesized by reacting a supported dithioester with ammonium hydrogensulphide in a polar solvent. A preliminary study on models has led to the determination of the reaction parameters. The nucleophilic properties of the benzodithioate anion allow numerous possibilities especially chemical modification of the copolymer and grafting with or without cross-linking.
In order to improve the permanence of the plasticizer in a poly(vinylchloride) (PVC) compound we have studied the free radical polymerization and grafting of decyl methacrylate (DMA) onto PVC in the presence of a lead stabilizer. The influence of different parameters has been investigated and homogeneous PVC-g-PDMA copolymers have been obtained. Their molecular weights and the glass transition temperatures were consistent with the grafted nature of the copolymers.
Les acrylates dithiocarboxyliques contrairement à leur homologue thiocarbonylé homopolymérisent difficilement par voie radicalaire pour donner des polymères à faible masse molaire. La copolymérisation est par contre facile et les essais conduits avec quelques monomères usuels ont permis de calculer les paramètres e et Q d'Alfrey-Price ainsi que les coefficients de reactivité pour les différents coupes étudiés. Les acrylates dithiocarboxyliques complètent la gamme des monomères dithiocarboxylés dont l'étude commencée il y a quelques années, a permis d'accéder à une nouvelle classe de polymères fonctionnalisés.
Des acrylates porteurs de groupes dithiocarboxyliques sont obtenus avec des rendements élevés par action du chlorure d'acryloyle sur le sel de sodium d'hydroxy dithiobenzoates d'alkyl. Parmi les differentes méthodes de synthèses de dithiobenzoates hydroxylés utilisées, les meilleurs résultats ont été obtenus par réaction du sulfure de carbone sur un phénate alcalin dans le DMSO et à partir d'hydroxy benzonitriles et thiols par une séquence d'hydrochloration-sulfuration.

AbstractQuartäre Ammoniumsalze von Dithiobenzoesäuren reagieren mit Alkyl‐ bzw. Arylhalogeniden oder ‐dihalogeniden unter Bildung von symm. oder unsymm. Dithio‐ bzw. Bisdithioestern.
The synthesis and the characterization of poly (methyl methacrylate) (PMMA) grafted to poly(vinyl chloride) (PVC) through benzodithioate groups are studied. Unlike results generally obtained with conventional free-radical initiators for systems involving PVC and MMA, high conversions, and grafting efficiencies are achieved with azobis-isobutyronitrile. The paper describes the synthesis of p-vinylbenzodithioate-containing PVC and the dependence of the characteristics of PVC-g-PMMA on the composition of the reaction mixture. Characterization of the graft copolymers includes UV and IR spectroscopy, GPC, and microstructure analysis by removal of PMMA side chains by aminolysis of dithioesters groups. Intrinsic viscosity, glass transition temperature, and thermal sensitivity were investigated to confirm the grafted nature of the copolymer.

The synthesis of appropriate monomers bearing alkylidyne tricobaltnonacarbonyl cluster or sulfido tricobalt heptacarbonyl cluster is described. Organometallic copolymers are obtained by free-radical copolymerisation with other vinyl monomers. Direct metallation of macromolecules containing the dithioester or the thioamide functional groups was also studied. We show that the copolymerisation method is more convenient for the synthesis of pure materials containing a variable amount of definite cluster units. The potentiality of these new organometallic polymers with regard to homogeneous catalysis and for the modification of electrode surfaces is also discussed.
Les polythioamides aromatiques sont accessibles par polycondensation des bis(dithioesters) d'alkyle et/ou de carboxyméthyle avec des diamines aromatiques ou aliphatiques en milieu aqueux ou organique. Nous avons précisé l'influence du noyau aromatique sur le comportement du polymère en solution et sur quelques caractéristiques thermiques des polycondensats. Leur stabilité thermique est sensiblement améliorée par rapport à celle des composés aliphatiques, surtout lorsque cycle et groupements fonctionnels sont conjugués entre eux.

Les bis(n-dodécyle dithiocarboxylates) sont accessibles en deux étapes à partir des dinitriles avec des rendements souvent excellents; ces composés sont cristallisés, stables et stockables et leur haute pureté permet de les utiliser pour la polycondensation avec les diamines. Les tétrathioadipates se dégradent facilement en milieu basique pour donner, entre autres, un dithioester conjugué suivant une réaction comparable à la cyclisation, de Dieckmann des diesters, et leur cas a été étudié en détail.
