Catalyst system for olefinic polymerization |
摘要 |
A new improved catalyst system for alpha-olefin type polymerizations includes a metal di- or tri-halide compound of Al, Ga, or In and a diorganomagnesium compound in combination with a Group IVB-VIII transition metal compound. The improved catalyst system provides increased polymerization activity and polymers having a high degree of isotactic stereoregularity.
