Abstract

Four of 9,10-dihydroanthracene-9,10-α,β-alkyl succinates have been synthesized and used as internal electron donors in MgCl2-supported Ziegler-Natta catalysts. The performances of the catalysts on the propylene polymerization have been investigated. The obtained polymers possess high-isotacticity and the polymerization activity is comparable with the catalysts using 9,9-bis(methoxymethyl)fluorene and diisobutyl phthalate as internal donor. With dimethoxydiphenylsilane as external donor, the catalysts for the polymerization of propylene exhibit satisfactory activities and are sensitive toward hydrogen. © 2010 Wiley Periodicals, Inc.
