Solid catalyst component for olefin polymerization

Claim 1

A solid catalyst component for olefin polymerization which is produced by reacting (A) a silicon compound selected from the group consisting of (1) halogen-containing silicon compounds, (2) silicon compounds having a monomer unit --SiR 2 R 3 O-- (wherein R 2 and R 3 may be same or different, R 2 is an alkyl group, an aryl group, a cycloalkyl group, an alkoxy group, or an aryloxy group and R 3 is an alkyl group, an aryl group, a cycloalkyl group, or a hydrogen atom and a polymerization degree of 2 to 10,000, (3) silanols represented by the general formula R l 4 Si(OH) 4-l (wherein R 4 is an alkyl group, an aryl group, a cycloalkyl group or a hydrogen atom and l is 1, 2 or 3) or condensation products of said silanols, (4) silicon compounds represented by the general formula R m 5 Si(OR) 6 ) 4-m (wherein R 5 is an alkyl group, an aryl group, a cycloalkyl group, an alkenyl group or a hydrogen atom, R 6 is an alkyl group, an aryl group or a fatty acid moiety and m is 1, 2 or 3), and (5) silicon compounds or polymers represented by the general formula [SiO a (OR 7 ) b ]n (wherein R 7 is an alkyl group, a cycloalkyl group, an aryalkyl group, an aryl group or a fatty acid moiety, a is a number defined by 0≦a≦1, b is a number defined by 2≦b≦4, number of and n is a 1 to 10,000) with (B) a compound of a transition metal of Groups IVa, Va and VIa of the periodic table to obtain a reaction mixture (I), reacting the reaction mixture (I) with (C) an organomagnesium compound selected from organomagnesium compounds or hydrocarbon-soluble complexes between an organomagnesium compound and an organometal compound capable of allowing said organomagnesium compound to be soluble in hydrocarbons to obtain an intermediate product (II), and contacting the intermediate product (II) with (D) an organoaluminum halide compound represented by the general formula R c 1 AlX 3-c (wherein R 1 is an organic group containing 1 to 20 carbon atoms, X is a halogen and c is a number defined by 0<c<3) and (E) an oxidative compound.
