Abstract: Process for the preparation of a syndiotactic propylene copolymer A syndiatactic propylene copolymer is obtained in high yields by copolymerization of propylene with small amounts of other olefins in the presence of a catalyst comprising a metallocene of the formula I (see formula I) in which M1 is titanium, zirconium, hafnium, vanadium, niobium or tantalum and an aluminoxane. This copolymer has a very high molecular weight, a very narrow molecular weight distribution, very high syndiotaxicity, advantageously low melting points and rubber-like behavior. Molded articles produced from the polymer are distinguished by high transparency, flexibility and tear strength. Their main areas of application are packagings of any type.

Abstract: Process for the preparation of a high molecular weight olefin polymer A very active catalyst system for olefin polymerization is composed of an aluminoxane and a metallocene of the formula I (see formula I) wherein preferably M1 is Zr or Hf, R1 and R2 are alkyl or halogen, R3 and R4 are hydrogen, R5 and R6 are alkyl or haloalkyl, -(CR8R9)m-R7-(CR8R9)n- is a single-membered or multimembered chain in which R7 may also be a (sub- stituted) hetero atom, and m+n is zero or 1. The catal- yst system gives polymers having a high molecular weight and high stereospecificity.

Abstract: A syndiotactic polyolefin which is obtained in high yield by polymerising or copolymerising an olefin of the formula R -CH=CH-R in the presence of a catalyst comprising a metallocene of the formula I in which M is titanium, zirconium, vanadium, niobium or tantalum, and an aluminoxane. This polyolefin has a very high molecular weight, a very narrow molecular weight distribution and very high syndiotacticity. Mouldings produced from the polymer have high transparency, flexibility and tear strength and excellent surface gloss.

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: Syndio-iso block polymers of 1-olefins containing molecular chains in which syndiotactic and isotactic sequences are present are obtained if a catalyst which comprises a bridge-containing chiral metallocene of the formula I and an aluminoxane is used for the polymerisation of the 1-olefins. Some of the polymers have rubber-like properties.
