    摘要： Methods of forming a catalyst, catalysts, polymerization processes and polymers formed therefrom are described herein. The method of forming a catalyst generally includes contacting an alkyl magnesium compound with an alcohol to form a magnesium alkoxide compound; contacting the magnesium alkoxide compound with a first titanium alkoxide and a first agent to form a reaction product “A”, wherein the titanium alkoxide and the first agent are nonblended individual components prior to contacting the magnesium alkoxide; and sequentially contacting the reaction product “A” with a second agent, followed by a third agent, and subsequently a first reducing agent to form a catalyst component.

    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.

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 two or more co-supported metallocenes.
