Metallocene Catalyzed Copolymerization of Olefins with Functional Monomers. ActaPolytechnica Scandinavica Chemical Technology Series No. 245

摘要

The copolymerization of olefins with polar compounds and styrene was investigatedusing titanium and zirconium based metallocine catalysts in combination with methylaluminoxane. The attempted copolymerization of ethylene and styrene with the catalyst system CpTiCl3/MAO produced a mixture of syndiotactic polystyrene, high density polyethylene, and oligomers; no high molar mass copolymer of ethylene and styrene was detected. The formation of separate polymer fractions indicated that the catalyst contained multiple active species.
