Process for preparing copolymers and blend compositions containing the same

摘要

A process for the preparation of blends comprising an ethylene copolymer, which is prepared by polymerizing ethylene and at least one comonomer selected from (a) a compound represented by the formula H₂C-CHR, wherein R is an alkyl group, an aryl group, or (b) a diene. The polymerization takes place 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.
