Zusammenfassung:	A new improved catalyst system for alpha-olefin type polymerizations includes a metal alkyl compound selected from the group consisting of R2WY or R3W and organomagnesium compound R'MgX in combination with a Group IVB-VIII transition metal compound. The improved catalyst system prevides both increased polymerization activity and polymers having a high degree of isotactic stereoregularity.
