Abstract

On produit des polyalcénamères en polymérisant des cycloalcènes par ouverture de noyau. La polymérisation s'effectue en présence d'un système catalyseur homogène comprenant (a) un sel d'un métal de transition choisi dans le groupe VIb du tableau périodique; (b) un composé organométallique de métal choisi dans les groupes III et IVa du tableau périodique; et (c) un polymère organo-silique représenté par la formule (Ia), (Ib) ou (Ic), R étant identique ou différent et représentant un atome d'hydrogène, un groupe phényle ou alkyle C¿1?-C¿4?; R' représentant un groupe phényle ou alkyle C¿1?-C¿4?; 0?x?3; 0?y?4; z=0 ou 1; y+z?1; x+y+z=4; le rapport molaire entre le composant (c) et le composant (a) étant d'au moins 0,5:1. Le système catalyseur selon l'invention permet d'augmenter sensiblement la vitesse de polymérisation.
