PROCESS FOR PREPARING IN A SINGLE REACTOR POLYMER BLENDS HAVING A BROAD MOLECULAR WEIGHT DISTRIBUTION

摘要

Ethylene-based polymer blends having an MWD of at least 2 were made in a single reactor using a mixed constrained geometry catalyst (CGC) system. The process comprises the steps of contacting under polymerization conditions and in a single reaction vessel (i) ethylene, (ii) at least one C3-C20α-olefin, (iii) optionally, at least one polyene, and (iv) a mixed CGC system.
