| 摘要 |
The objective of the present invention is to provide a solid catalyst component and a catalyst for polymerization of olefins, which shows a high activity, can lower the rate of forming a polymer having a low molecular weight or a low stereoregular polymer which is soluble in a polymerization solvent and can obtain a high stereoregular polymer in a high yield.The present invention is a solid catalyst component(A) for polymerization of olefins prepared by contacting (a) dialkoxymagnesium, (b) a titanium compound, (c) a diester of an aromatic dicarboxylic acid, (d) an aromatic hydrocarbon and (e) an organic silicon compound containing a hydroxyl group, and a catalyst for polymerization of olefins prepared from the solid catalyst component (A) , an organic aluminum compound (B) represented by the general formula R2pAlQ3-p and an organic silicon compound (C) represented by the general formula R3qSi(OR4)4-q.
