Abstract: A syndiotactic polyolefin is obtained in a high yield by polymerization or copolymerization of an olefin of the formula Ra-CH=CH-Rb in the presence of a catalyst consisting of a metallocene of the formula I (I) and an aluminoxane. This polyolefin has a very high syndiotactic index. At a low polymerization temperature, a polyolefin having a low average molecular weight and narrow molecular weight distribution is obtained, and at a high polymerization temperature a polymer having a high average molecular weight and a wide molecular weight distribution is obtained. Shaped articles produced from the polymers are distinguished by a high transparency, flexibility, tear strength and excellent surface gloss.

Abstract: 1-olefin polymer waxes having a very narrow molecular weight distribution, high isotacticity, a narrow particle size distribution and high bulk density are obtained by means of a catalyst which comprises a chiral, stereorigid metallocene compound and an aluminoxane, in the presence of small amounts of nitrogen during the polymerisation.

Abstract: A polyolefin moulding composition essentially comprising from 20 to 99 % by weight, based on the moulding composition, of an isotactic polyolefin containing no atactic polymer chains and from 1 to 80 % by weight, based on the moulding composition, of a rubber having a glass transition temperature of below -20 DEG C is distinguished by high impact strength and hardness even at low temperatures.

Abstract: Syndiotactic polyolefins having a molecular weight distribution Mw/Mn of >/= 3, which may be monomodal, bimodal or multimodal, are obtained by polymerisation or copolymerisation of olefins of the formula RCH=CHR in which a catalyst system comprising an aluminoxane and a transition-metal component (metallocene) is used, where the transition-metal component comprises at least 2 metallocenes of the formula which are stereorigid and whose moiety formed by Zr and the substituents R - R has Cs symmetry or slightly distorted Cs symmetry.
