Abstract: Biaxially oriented polypropylene film having improved tear propagation resistance A biaxially oriented polypropylene film is described. The base ply of the film essentially consists of a polypropylene prepared by means of a metallocene catalyst. This polypropylene is distinguished by a mean isotactic block length of greater than 40, an n-heptane soluble fraction of less than 1% and a ratio of the weight average molecular weight Mw to the number average molecular weight Mn of less than 4.

Abstract: The present invention relates to a metallocene compound of the formula I R5nCp1Cp2M1R1R2 (I) where Cp1 and Cp2 are, independently of one another, identical or different and are each an unsubstituted or substituted cyclopentadienyl group, n = zero or 1, R5 is a bridge, M1 is a metal of group IVb, Vb or VIb of the Periodic Table of the Elements, R1 and R2 are identical or different and are each a hydrogen atom or a C1-C40-group, wherein at least one of the two groups Cp1 and Cp2 is a substituted cyclopentadienyl group which bears at least one cyclic C1-C30-group containing at least one heteroatom in the ring, or which bears a fused-on C2-C30 ring system containing at least one heteroatom in the ring. The metallocene compound can be used as a catalyst component for olefin polymerization.

Abstract: The invention relates to supported metallocene catalyst systems, optionally prepolymerized with olefinic monomer, preferably ethylene or propylene, useful in the polymerization of propylene to isotactic polyproylene. The isotactic polypropylene obtained generally has a molecular weight of about 100000 g/m or greater, a melting point of about 140 DEG C or greater and granular morphology. The supported catalyst system generally has high catalytic activity, and upon use in a polymerization reactor results in a process with minimal to no reactor fouling, fining, or chunking.

Abstract: Polyolefins having a molecular weight distribution Mw/Mn of >/= 3, which can be monomodal, bimodal or multimodal, are obtained by polymerisation or copolymerisation of olefins using a catalyst system comprising an aluminoxane and a transition-metal component (metallocene), where the transition-metal component comprises at least one zirconocene of the formula I and at least one zirconocene of the formula Ia or alternatively at least 2 zirconocenes of the formula I.
