Abstract
A catalyst for olefin polymerization comprising (A) a solid catalyst component which is prepared by causing (a) a magnesium compound, (b) a tetravalent titanium halide compound, and (c) an electron donor compound to come in contact with each other, (B) an organoaluminum compound of the formula R1pAlQ3-p, and (C) an organosilicon compound of the formula SiR2R3(OR4)(OR5), and (D) an organosilicon compound of the formula R6xSi(OR7)4-x exhibits a higher hydrogen activity than conventional catalysts.
