Supported chromium oxide/boron catalyst |
摘要 |
A catalyst system useful for the polymerization of ethylene and other alpha -olefins comprising (a) a silica-supported chromium oxide catalyst and (b) a dihydrocarbylboron monohydrocarbyloxide adjuvant. The catalyst system results in alpha -olefin polymers having a broadened molecular weight distribution in the high molecular portion. |
