Organic-inorganic hybrid supported zirconocene catalysts for ethylene polymerization

Monomeric silica (SM) and silica-poly[3-(trimethoxysilyl)propyl methacrylate-co-4-vinylpyridine] inorganic-organic hybrid (SMV) have been synthesized, and by loading zirconocene catalyst on the carrier, novel zirconocene supported catalyst has been made and tested for ethylene polymerization. Ethylene polymerization data demonstrate that the SMV supported catalyst has higher activity than the SM supported one.
