SELF LIMITING CATALYST COMPOSITION AND PROPYLENE POLYMERIZATION PROCESS |
摘要 |
A catalyst composition for the polymerization of propylene comprising one or more Ziegler-Natta procatalyst compositions comprising one or more transition metal compounds and one or more esters of aromatic dicarboxylic acid internal electron donors; one or more aluminum containing cocatalysts; a selectivity control agent (SCA) comprising at least one silicon containing compound containing at least one C1- 10 alkoxy group bonded to a silicon atom, and one or more activity limiting agent (ALA) compounds comprising one or more aliphatic or cycloaliphatic carboxylic acids; alkyl-, cycloalkyl- or alkyl(poly) (oxyalkyl)- (poly)ester derivatives thereof; or inertly substituted derivatives of the foregoing.
