CA 2245159

A process for the preparation of a copolymer of carbon monoxide with an olefinically unsaturated compound, comprising copolymerizing the monomers in the presence of a Group VIII metal containing catalyst composition and in the presence of an olefinically unsaturated compound (A) which contains in its molecular structure an organic group imparting steric hindrance on the vinyl group. A copolymer obtainable by the said process.

Ce procédé de préparation d'un copolymère de monoxyde de carbone et d'un composé alcénique consiste à copolymériser les monomères en présence, d'une part, d'une composition de catalyseur contenant un métal du groupe VIII et, d'autre part, d'un composé (A) alcénique comprenant dans sa structure moléculaire un groupe organique transmettant l'empêchement stérique au groupe vinyle. On décrit également le copolymère obtenu à l'aide dudit procédé.
