ABSTRACT:
A solid catalyst component for olefin copolymerization containing trivalent titanium compound, which is obtained by reducing a titanium compound represented by the general formula Ti(OR.sup.1).sub.n X.sub.4-n (wherein R.sup.1 is a hydrocarbon group of 1 to 20 carbon atoms, X is a halogen atom, and n is a number satisfying 0<n.ltoreq.4) with an organomagnesium compound in the presence of a porous carrier having a pore volume of, at pore radius of 50 to 5,000 .ANG., at least 0.2 ml/g, or in the presence of an organosilicon compound having at least one Si-O bond and the porous carrier to obtain a solid product, treating the solid product with a mixture of an ether compound and titanium tetrachloride, a catalyst system for olefin copolymerization comprising the above-mentioned solid catalyst component and an organoaluminum compound, as well as a process for olefin copolymerization using said catalyst system.
