    摘要： Supported stereospecific catalysts and processes for the stereotactic propagation of a polymer chain derived from ethylenically unsaturated monomers such as the polymerization of propylene to produce syndiotactic polypropylene or isotactic polypropylene. The supported catalyst comprises a stereospecific metallocene catalyst component and a co-catalyst component comprising an alkylalumoxane. Both the metallocene catalyst component and the co-catalyst component are supported on a particulate polyamide support comprising spheroidical particles of a polyamide having an average diameter with the range of 5-60 microns, and a porosity permitting distribution of a portion of the co-catalyst within the pore volume of the polyamide particles while retaining a substantial portion on the surface of the particles. The polyamide support is characterized by relatively low surface area, specifically a surface area less than 20 square meters per gram. The metallocene component can take the form of a single metallocene or two or more co-supported metallocenes.

    摘要： A process for the preparation of a supported metallocene catalyst incorporating metallocene and co-catalysts components on a support. There is provided a particulate catalyst support material in which an alumoxane co-catalyst is incorporated onto the support particles and contacted with a dispersion of a metallocene catalyst in an aromatic hydrocarbon solvent. The metallocene solvent dispersion and the alumoxane-containing support are mixed at a temperature of about 10° C. or less for a period sufficient to enable the metallocene to become reactively supported on the alumoxane support material. The supported catalyst is recovered from the aromatic solvent and then washed optionally with an aromatic hydrocarbon and then sequentially with a paraffinic hydrocarbon solvent at a temperature of about 10° C. or less. The washed catalyst is dispersed in a viscous mineral oil having a viscosity which is substantially greater that the viscosity of the paraffinic hydrocarbon solvent.
