Abstract: A catalyst of high activity and stereospecificity in alpha -olefin polymerization is obtained when titanium trichloride, prepared from titanium tetrachloride by reduction with an aluminum alkyl halide, is thermally treated, first with an ether in the presence of a cyclopolyene and the solid reaction product is then treated with an aluminum alkyl halide in the presence of a small amount of a cyclopolyene and/or an olefin. With the catalyst obtained high space-time yields of alpha -olefin polymers and copolymers can be produced.

Abstract: A catalyst of high activity and stereospecificity in alpha -olefin polymerization is obtained by subjecting titanium trichloride, obtained by reduction of titanium tetrachloride with aluminum alkyl halides, to two thermal treatments, the second thermal treatment being carried out in the presence of a dialkyl ether.
