    摘要： Method employing a supported metallocene catalyst composition in the production of an isotactic ethylene propylene co-polymer. The composition comprises a metallocene component supported on a particulate silica support having average particle size of 10-40 microns, a pore volume of 1.3-1.6 ml/g, a surface area of 200-400 m 2/g. An alkylalumoxane cocatalyst component is incorporated on the support. The isospecific metallocene is characterized by the formula: B(CpRaRb)(FlR′2)MQn   (1) or by the formula: B′(Cp′R′aR′b)(Fl′)M′Q′n′   (2) In the formulas Cp and Cp′ are substituted cyclopentadienyl groups, Fl and Fl′ are fluorenyl groups, and B and B′ are structural bridges. R′ are substituents at the 2 and 7 positions, Ra and R′a are substituents distal to the bridge, and Rb and R′b are proximal to the bridge. M and M′ are transition metals, Q′ is a halogen or a C1-C4 alkyl group; and n′ is an integer of from 0-4.

    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 polyorganosilsesquioxane support comprising spheroidal particles of a polyorganosilsesquioxane having an average. diameter with the range of 0.3-20 microns. The polyorganosilsesquioxane support is characterized by relatively low surface area, specifically a surface area less than 100 square meters per gram. The metallocene component can take the form of a single metallocene or two or more metallocenes which are co-supported on the polyorganosilsesquioxane support.

    摘要： Catalyst Systems, processes of forming the same and polymers and polymerization processes are described herein. The process of forming the catalyst system generally includes providing a first compound including a magnesium dialkoxide and aluminum alkoxide: contacting the first compound with a first agent and a second agent to form a solution of reaction product “A”, the first agent including a titanating agent and the second agent including a first metal halide; contacting the solution of reaction product “A” with a third agent to form a solid reaction product “B”, the third agent including a second metal halide: contacting the solid reaction product “B” with a fourth agent to form a solid reaction product “C”, the fourth agent including a third metal halide: optionally contacting the solid reaction product “C” with a fifth agent to form a solid reaction product “D”, the fifth agent including a fourth metal halide; and contacting the solid reaction product “C” or “D” with a sixth agent to form a catalyst component, the sixth agent including a first organoaluminum compound.
