SOLID CATALYTIC COMPONENT AND CATALYST FOR POLYMERIZING OLEFINS

摘要

The present invention provides a solid catalyst component (A) obtained by allowing a dialkoxymagnesium or diaryloxymagnesium, a titanium compound, a diester of aromatic dicarboxylic acid and a cyclic or chain polysiloxane to come in contact with one another. Further, the present invention provides a catalyst for polymerization of olefins prepared from the foregoing solid catalyst component (A), an organic aluminum compound and an organic silicon compound. <IMAGE>
