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: of the disclosure HOE 87/F 229 In the case of Ziegler catalysts based on a metallocene as the transition metal component and an aluminoxane as the activator, preactivation of the metallocene with the aluminoxane results in a considerable increase in the activity of the catalyst system. Furthermore, 1-olefin polymers of a high degree of isotacticity and having compact, spherical particles, a very narrow particle size distribution and a high bulk density are obtained by means of a catalyst system of this type.
