Patent

CA 2342788

The invention provides a resin composition comprising a crosslinking silyl-terminated stellar-structure vinyl polymer or a stellar-structure vinyl block copolymer or chain-extended vinyl block copolymer. The invention provides a method of producing a stellar-structure vinyl block copolymer or chain-extended vinyl block copolymer which comprises forming a block copolymer using living radical polymerization and adding a compound having two or more polymerizable carbon-carbon double bonds at the end point of polymerization of the block copolymer.

L'invention porte sur une composition de résine, comportant soit un polymère de vinyle à structure étoilée présentant groupe silyle à l'une de ses extrémités, soit un copolymère bloc de vinyle à structure étoilée ou à chaîne allongée, et sur un procédé de production d'un copolymère bloc de vinyle à structure étoilée ou à chaîne allongée consistant à effectuer une polymérisation de radicaux vivants pour former un copolymère bloc, puis à ajouter au point final de la polymérisation un composé à plusieurs liaisons doubles C-C polymérisables.
