Olefin polymerization catalyst |
| abstract |
An olefin polymerization catalyst comprising (A) a solid catalyst component and (B) an organometallic compound component. The solid catalyst component (A) is prepared by a process comprising the steps of: (I) obtaining a solid (A-1) by reacting: (i) an organomagnesium component soluble in a hydrocarbon solvent and represented by the formula (M1) alpha (Mg) beta (R1)p(R2)q(OR3)r; and (ii) an Si-H bond-containing chlorosilane compound represented by the formula: HaSiClbR44-(a+b), in a ratio of from 0.01 to 100 mol (ii) per mol (i); (II) reacting the solid (A-1) with an alcohol (A-2) in a ratio of from 0.05 to 20 mol of the alcohol per mol of C-Mg bonds contained in the solid (A-1), to form a reaction product; and (III) reacting the reaction product with a titanium compound (A-4). The solid catalyst component (A) is adjusted to have an alkoxy group/titanium molar ratio of 2.4 or lower and an alkoxy group/magnesium molar ratio of 0.15 or lower. |
