Syndiotactic homopolymers of olefins.

摘要

Homopolymers of olefins having from 4 to 10 carbon atoms in which the microstructure of the polymer chain consists of blocks of repeating recemic dyads predominantly connected by units consisting of a meso triads. Also disclosed is a process for preparing said homopolymers by metallocene catalysis using an asymmetric bridged dicyclopentadienyl derivative of a metal of groups 4b, 5b or 6b.
