ABSTRACT OF THE DISCLOSURE A titanium trichloride catalyst complex is produced by reducing titanium tetrachloride with an organo-metal compound and then treating the resulting reduced solids product with a chlorinated hydrocarbon having at least three carbon atoms in the presence of a complexing agent. The resulting titanium trichloride complex composition, when employed as co-catalyst with an organo-metal compound for Ziegler-type catalysts in polymerization of .alpha. olefins, results in uniform polymer grains with unexpectedly high polymerization activity and high stereo- regular polymer yield ratios.
