Title (EN) PROCESS FOR COAGULATING FLUOROELASTOMERS
(FR) PROCÉDÉ DE COAGULATION D'ÉLASTOMÈRES FLUORÉS
Abstract: front page image
(EN)In a process for the manufacture of fluoroelastomers, a coagulant is employed that is a water-soluble polymer having at least 2 quaternary onium centers. Specific examples of such coagulants include, but are not limited to poly(diallyldimethylammonium chloride), poly(epichlorohydrin-co-dimethyl amine), and poly(acrylamide-co-diallyldimethylammonium chloride).
(FR)L'invention concerne un procédé de fabrication d'élastomères fluorés, dans lequel un coagulant, qui est un polymère hydrosoluble ayant au moins 2 centres d'onium quaternaire, est utilisé. Des exemples spécifiques de tels coagulants comprennent, sans s'y limiter, du chlorure de polydiallyldiméthylammonium, de la polyépichlorhydrin-co-diméthylamine, et du chlorure de polyacrylamid-co-diallyldiméthylammonium.
