ABSTRACT:
A new improved Ziegler type catalyst system for alpha-olefin type polymerization includes R'.sub.3 Y or R'.sub.2 YX and mixtures thereof, at least one Group IVB -VIII transition metal halide and an alkyl metal compound selected from R'.sub.2 YNR.sub.2 and R'XYNR.sub.2, wherein Y is Al, Ga or In and at least one Lewis base. The improved catalyst system provides increased polymerization activity without significantly affecting the crystallinity of the polymer.
