A Sight into the Mechanism of Tantalum Catalyzed Ethylene Polymerization, Separated Ta(III) Compound on Silica Surface as Direct Active Species for Ethylene Polymerization

A brand-new Ta(III) catalyst for polymerization has been developed, which similar to the philips catalyst, and Ta(III) was proved as the active species with solid evidence in the ethylene polymerization, the reaction mechanism also has been systematically studied.
