Disclosed is a curing composition containing the following three components: (A) a vinyl polymer (I) containing at least one group represented by the general formula (1) below at the end of the molecule: CH2=C(Ra)-C(O)O- (1) (wherein Ra represents a hydrogen or a monovalent organic group having 1-20 carbon atoms); (B) a polymerization initiator; and (C) a metal soap. The curing composition contains a vinyl polymer and has excellent mold releasability while scarcely deteriorating mechanical properties such as compression set.
L'invention concerne une composition durcisseuse contenant les trois ingrédients composants suivants : (A) polymère de vinyle renfermant au moins un groupe représenté par la formule générale (1) ci-après en bout de molécule : CH¿2?=(R?a¿)-(CO)O- (dans laquelle R?a¿ représente hydrogène ou un groupe organique monovalent comptant de 1 à 20 atomes de carbone) ; (B) un initiateur de polymérisation ; et (C) un savon métallique. La composition durcissante comprend un polymère de vinyle et possède une remarquable capacité de démoulage, pour des propriétés mécaniques telles que la déformation rémanente après compression pratiquement intactes.
