摘要：
A series of heterogeneous catalysts by loading metallocenes on surface of alpha-Ti(HPO4)(2), a kind of solid acid, has been synthesized. Polymerization of alkenes, including ethylene and propylene, based on participation of the heterogeneous catalysts were studied and the results were compared to metallocenes supported on silica gel, alpha-Zr(HPO4)(2) and clay. Higher catalytic activity, larger polymer molecular weight and narrow distribution of polymer molecular weight were obtained. Acidic strength of the support and its influence to metallocenes were studied to discover intrinsic factors in the polymerizations. (C) 2016 Elsevier B.V. All rights reserved.
