Title (EN) PROCESS FOR THE POLYMERIZATION OF VINYL CHLORIDE
(FR) PROCÉDÉ DE POLYMÉRISATION DU CHLORURE DE VINYLE
Abstract:
(EN) In a process for the aqueous suspension polymerization of vinyl chloride, alone or in mixture with other monomers, in the presence of at least one of dialkylperoxydicarbonate, peroxyester and diacyl peroxide, the polymerization composition according to the invention comprises at least one dialkylhydroxylamine as a shortstopping agent along with a totally or partially hindered phenolic antioxidant.
(FR) La présente invention concerne un procédé de polymérisation en suspension aqueuse du chlorure de vinyle, seul ou mélangé à d'autres monomères, en présence de peroxydicarbonate de dialkyle et/ou de peroxyester et/ou de peroxyde de diacyle, la composition de polymérisation selon l'invention comprenant au moins une dialkylhydroxylamine comme agent d'interruption de polymérisation ainsi qu'un antioxydant phénolique totalement ou partiellement encombré stériquement.
