<p>A solid catalyst component (A1) for polymerization of olefins prepared by contact with a solid component (d) obtained by allowing (1) a solid component (a) obtained by allowing (i) a dialkoxymagnesium or diaryloxymagnesium, (ii) a titanium compound and (iii) a diester of aromatic dicarboxylic acid to come in contact with one another and (2) a solid component (b) obtained by allowing (i) a dialkoxymagnesium or diaryloxymagnesium, (ii) a titanium compound, (iii) a diester of aromatic dicarboxylic acid and (iv) a polysiloxane to come in contact with one another to come in contact with each other, or a solid catalyst component (A2) for polymerization of olefins prepared by allowing said solid component (a) and (3) a solid component (d) obtained by allowing (i) a dialkoxymagnesium or diaryloxymagnesium, (ii) a titanium compound, (iii) a diester of aromatic dicarboxylic acid, (iv) a polysiloxane and (v) an aluminum compound to come in contact with one another to come in contact with each other. A catalyst for polymerization of olefins prepared from the solid catalyst component (A1) or (A2), an organic aluminum compound (B) and an organic silicon compound (C).</p> |
