摘要 |
A catalyst of high activity and stereospecificity in alpha -olefin polymerization is obtained when titanium trichloride, prepared by reduction with aluminum alkyl halides, is treated first with an ether and then, without separation of the ether, with an aluminum alkyl halide in the presence of a small amount of a cyclopolyene and/or an olefin.
