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: 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: A biaxially oriented polypropylene film is described. The base ply of the film contains at least 90% by weight 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 disclosed heat-sealable, layered film comprises a polyolefinic base layer and at least one outer layer. The outer layer comprises a propylene-olefin copolymer prepared by means of a metallocene catalyst. The film is prepared by coextruding melts corresponding to the indiviaual layers of the film, taking off the coextruded film over a take-off roll whose temperature is between 10 and 90.degree.C, biaxially stretching and then heat-setting the resulting film, and optionally corona- or flame-treating the film, then winding it up in a wind-up unit.
