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: - 1 - HOE 89/F 083 of the disclosure A process for the preparation of a syndiotactic polyolefin A syndiotactic polyolefin is obtained in a high yield by polymerization or copolymerization of an olefin of the formula R"-CH=CH-R4 in the presence of a catalyst consisting of a metallocene of the formula I (I) in which M1 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 a very high syndiotactic index. Shaped articles produced from the polymer are distinguished by a high transparency, flexibility, tear resistance and an excellent surface gloss.

Abstract: HOE 88/F 348 of the disclosure Process for the preparation of a heterogeneous metallocene catalyst component. The invention relates to a process for the preparation of a heterogeneous metallocene catalyst component from a suitably substituted metallocene of the sub-group 4 of the Periodic Table of the Elements and from poly(methylhydrogensiloxane) under the concomitant action of a catalyst. The metallocene component and a suitable aluminoxane can be used as catalyst for the polymerization of 1-olefins cyclic olefins, diolefins and cyclic diolefins.
