Abstract: 1-olefin polymer waxes having a very narrow molecular weight distribution, high isotacticity, a narrow particle size distribution and high bulk density are obtained by means of a catalyst which comprises a chiral, stereorigid metallocene compound and an aluminoxane, in the presence of small amounts of nitrogen during the polymerisation.

Abstract: A very effective catalyst system for olefin polymeriza- tion consists of a cocatalyst, preferably an aluminoxane, and a metallocene of the formula (I) in which, preferably, M1 is Zr, R1 and R2 are alkyl or halogen, R3 to R6 are alkyl, -(CR8R9)m-R7-(CR8R9)n- is a chain having one or more members, in which R7 can also be a (substituted) hetero atom, and m+n is zero or 1. The catalyst system leads to polymers of variable molecular weight and stereotacticity, depending on the substituents R3 to R6 chosen, at polymerization temperatures which are relevant in industry.

Abstract: 2-Substituted bisindenylmetallocenes, process for their preparation, and their use as catalysts in the poly- merization of olefins. The novel metallocenes of the formula I (see figure I) in which, 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- or multi- membered chain in which R7 may also be a (substituted) hetero atom, and m + n is zero or 1, form, together with aluminoxanes as cocatalysts, a very effective catalyst system for the preparation of polyolefins of high molecu- lar weight.

Abstract: -1- A propylene block copolymer having good flow properties and a very good low temperature impact strength is obtained in a high yield if a catalyst which consists of a chiral metallocene, containing a bridge, of the for- mula I and an aluminoxane is used for the polymerization of propylene and the comonomers. The polymerization is carried out in two stages, a crystalline propylene polymer being prepared in the first stage.

Abstract: Process for the preparation of a polyolefin Olefins of the formula R11-CH=CH-R12 (R11, R12 = H or C1-C14-alkyl) are polymerized in the presence of a catalyst consisting of at least one metallocene of the formula I (M = zirconium or hafnium) and an aluminoxane. Polymers having a high molecular weight are obtained in a high yield.

Abstract: 1-Olefin isoblock polymer and process for its manufacture Isoblock polymers of 1-olefins with a narrow molecular weight distribution are obtained when 1-olefins are polymerized using a catalyst consisting of a chiral metallocene, containing bridges, of formula I: (see fig. I) and an aluminoxane. The polymers have rubber-like properties.

Abstract: Propylene isoblock polymers with 0.5 to 10 mol%, based on the total polymer, of randomly distributed ethylene units and with a narrow molecular weight distribution are obtained when propylene is polymerized using a catalyst consisting of a chiral metallocene, containing bridges, of formula I: (I) and an aluminoxane. The polymers have rubber-like properties.
