Abstract
Novel TiCl.sub.3 catalytic complexes for the stereospecific polymerization of alpha-olefins and to a process for preparation of these catalytic complexes which are obtained by reduction of TiCl.sub.4 in the presence of a Lewis base which has preferably been complexed with the reducing agent. Furthermore, the present invention relates to a process for improved polymerization of alpha-olefins to crystalline polyolefins in high yields and high stereospecificity using these catalytic complexes.
