Catalytic component for olefin polymerization.

摘要

A catalytic component for olefin polymerization, produced by a process which comprises causing (A) magnesium metal, (B) a halogenated hydrocarbon represented by the general formula, RX [wherein R stands for an alkyl group, an aryl group, or a cycloalkyl group each having 1 to 20 carbon atoms and X for a halogen atom], and (C) a compound represented by the general formula, X1_nM(OR<1>)m-n [wherein X<1> stands for a hydrogen atom, a halogen atom, or a hydrocarbon group having 1 to 20 carbon atoms, M for a boron, carbon, aluminum, silicon, or phosphorus atom, R<1> for a hydrocarbon group having 1 to 20 carbon atoms, m for the valency of M, and m > n >/= O] to contact (D) a halogen-containing alcohol and then contact (E) an electron donating compound and (F) a titanium compound thereby forming a titanium-containing solid substance, and causing said titanium-containing solid substance, in the presence of (G) an organic aluminum compound, to contact (H) an olefin thereby allowing said titanium-containing solid substance to incorporate therein a corresponding olefin polymer in a ratio in the range of 0.1 to 100 g per g of said titanium-containing solid substance.
