Patent

CA 2255754

Disclosed is a process for the preparation of an ethylene copolymer by copolymerizing ethylene and at least one comonomer selected from a compound represented by the formula H2C=CHR wherein R is an alkyl group or an aryl group, and a diene, in the presence of a solid catalyst system comprising a support, a transition metal compound and an activator capable of converting the transition metal compound into a catalytically active transition metal complex.

Cette invention concerne un procédé de préparation d'un copolymère d'éthylène obtenu par copolymérisation d'éthylène et d'au minimum un comonomère choisi parmi des composés ayant la formule H¿2?C = CHR, dans laquelle R est un groupe alkyle ou un groupe aryle et un diène, en présence d'un catalyseur solide comprenant un support, un composé métallique de transition et un activateur pouvant transformer le composé métallique en complexe métallique de transition catalytiquement actif.
