<p>A solid catalyst component for olefin polymerization comprising a hydraocarbon-isoluble product (III) obtained by reacting (A) a silicon compound selected from the group consisting of (1) silicon compounds represented by the general formula R1aR2bR3cSi, wherein R1, R2 and R3 are each an alkyl, cycloalkyl, aralkyl, aryl, alkoxy, aryloxy, or hydroxyl group or a halogen or hydrogen atom; and a, b and c are numbers defined by the formulas 0 ? a,b,c, ? 4 and a + b + c = 4; and (2) silicon compound containing the linkage Si-O-Si and polymers thereof with (B) a compound of a transition metal of Groups IVa, ? ? VIa of the periodic table to for ? react on mixture (I), further reacting the reaction mixture (I) with (C) an organomagnesium compound selected from simple organomagnesium compounds and hydrocarbonsoluble complexes thereof with an organometallic compound capable of solubilizing said organomagnesium compounds to produce an intermediate product (II), and contacting the intermediate product (II) with (D) a halogen-containing compound of a transition metal of Groups IVa, Va and VIa of the periodic table, to form the hydrocarbon-insoluble product (III).</p> |
