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: - 1 - HOE 88/F 061 Process for the preparation of a 1-olefin polymer A very efficient catalyst sy tem for the polymerization of 1-olefins consists of an aluminoxane and a metallocene which is a compound of the formula I (I) in which R1 and R2 denote hydrogen atoms, halogen atoms or hydrocarbon radicals and R3 and R4 are mononuclear or polynuclear hydrocarbon radicals which can form a sandwich structure with the central atom and which are linXed to one another by a -R6m-R5-R7n- bridge containing a hetexo atom and consisting of one or several members. The catalyst system, produces polymers having a high molecular weight and excellent grain morphology.

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.
