摘要:
Olefin is polymerized using a catalyst comprising a solid catalyst component and an organometallic compound, the solid catalyst component being prepared by reacting 1 a reaction product obtained by reacting the reaction product of Si oxide and/or Al oxide and Ti compound or both Ti compound and V compound (Ti.V component) with organic Al compound, with 2 a reaction product obtained by the reaction of Mg halide, a compound of the general formula Me(OR).sub.n X.sub.z-n and Ti.V component (optional component), and further reacting the reaction product of the above 1 and 2 with 3 a compound of the general formula R.sub.p Si(OR).sub.q X.sub.4-p-q.
