Abstract: Copolymerisation of propylene with ethylene or a 1-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, hafnium, vanadium, niobium or tantalum, and an aluminoxane gives a polypropylene moulding composition containing syndiotactic polymer chains in high yield. This moulding composition has a very high molecular weight, a very narrow molecular weight distribution and very high syndiotacticity. Mouldings produced from the moulding composition 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: HOE 88/F 384 of the disclosure: Bisindenyl derivate, and a process for the preparation thereof. A bisindenyl derivate of the formula I (I) (M1 = Si or Ge, R6 and R7 = unsubstituted or substituted indenyl radical) is obtained in very good yield by reacting a compound of the formula II (II) (X = halogen) with a compound of the formula III or IV R6 - M2 (III) R7-M2 (IV) (M2 = alkali metal) if, in the reaction, compound III or IV is added slowly to compound II. Compound I is suitable as a starting material for the preparation of metallocene catalyst components.
