Abstract

L'invention concerne notamment un procédé de copolymérisation du cis-1,3-pentadiène et du trans-1,3-pentadiène afin de préparer du cis-1,4-polypentadiène. D'autres dioléfines conjuguées, comprenant le butadiène, l'isoprène, le 2-éthyl-1,3-butadiène et le 2-méthyl-1,3-pentadiène, peuvent également être copolymérisées avec l'isomere de cis-1,3-pentadiène pour préparer des copolyrnères élastomères. L'invention concerne également un procédé de copolymérisation de l'isoprène avec le trans-1,3-pentadiène, et la préparation de cis-1,4-polypentadiène à teneur élevée en polymère cis-1,4, par polymérisation du cis-1,3-pentadiène. Le catalyseur de polymérisation utilisé dans toutes ces polymérisations est un système catalytique ternaire constitué de a. Un composé organométallique choisi parmi les trialkyl aluminium, les dialkyl magnésium et les dialkyl zinc, b. Un composé de chrome soluble, choisi parmi les sels de chrome d'acides organiques contenant de 2 à 20 atomes de carbone, les composés complexes organiques de chrome contenant des ligands tridentés et les composes organiques de chrome à liaison, et c. Un composé choisi parmi les phosphites acides de dialkyle, les phosphites acides de diaryle et le phosphite de tris(2-choroéthyle).
