Process for the manufacture of a catalyst |
摘要 |
A catalyst of high activity and stereospecificity in alpha -olefin polymerization is obtained by subjecting titanium trichloride, prepared from titanium tetrachloride by reduction with aluminum alkyl halides, to two thermal treatments, the second one being carried out in the presence of an dialkyl ether and a cyclopolyene, and/or after-treating the solid reaction product with an aluminum alkyl halide, optionally in the presence of a small amount of a cyclopolyene and/or an olefin.
