SYNDIOTACTIC COPOLYMERS OF PROPYLENE AND OLEFINS

摘要

Copolymers of propylene and olefins having from 2 to 10 carbon atoms in which the microstructure of the side chain is highly syndiotactic, more particularly random copolymers. Also disclosed is a process for preparing said copolymers by metallocene catalysts using an asymmetric bridged dicyclopentadienyl derivative of a metal of groups 4b, 5b, or 6b.
