Abstract
Extremely strong, i.e., non-friable TiCl.sub.3 Ziegler-type polymerization catalyst are obtained by prepolymerizing a reduced solid TiCl.sub.3 product with a mixture of propylene and linear C.sub.8 -C.sub.18 alpha-olefin to produce a reduced solid TiCl.sub.3 product containing 5 to 35 weight percent of a copolymer of propylene and C.sub.8 -C.sub.18 alpha-olefin having a ratio of the infrared spectrum of the copolymer at 720 cm.sup.-1 : the infrared spectrum of the copolymer at 975 cm.sup.-1 in the range of 0.04 to 0.20.
