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 translation: 当通过用烷基卤化铝还原形成的四氯化钛的三氯化钛进行热处理时，首先用环己烯存在下的醚和固体反应产物是热处理，得到在α-烯烃聚合中具有高活性和立体定向性的催化剂 然后在少量的环烯烃和/或烯烃的存在下用烷基卤化铝处理。 通过催化剂得到高空时收率的α-烯烃聚合物和共聚物可以生产出来。

Abstract: A catalyst system of such high efficiency that the purification of the polymer can be dispensed with is obtained by first reacting a magnesium halide with an electron donor and/or a cyclopolyene, bringing the product obtained into contact with a TiCl.sub.3 -containing compound and using a stereoregulator. The system has a high stereospecificity whereby the proportion of atactic polymer is kept low. No excess amount of transition metal halides is required and the polymer obtained has uniform coarse particles and a very low halogen content. spThis is a continuation, of application Ser. No. 54,922 filed July 5, 1979, now abandoned.

Abstract: A polypropylene molding composition having an excellent impact strength at a temperature down to -60.degree. C and simultaneously a good hardness contains from 70 to 90% by weight of a polypropylene, 2 to 10% by weight of an ethylene propylene copolymer and 8 to 25% by weight of a polyethylene and is distinguished by a melt index MFI 230/5 lower than that of the polypropylene contained therein and simultaneously higher by the coefficient 1.3 to 7.0 than that of a polypropylene prepared in the presence of the same catalyst as the molding composition and having the same RSV.
