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, X1nM(OR¹)m-n [wherein X¹ 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, R¹ 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.
一种用于烯烃聚合的催化元件,由以下工艺制得:(A)金属镁;(B)通式为RX[其中R代表烷基、芳基或环烷基,每个环烷基有1至20个碳原子,X代表卤素原子]的卤代烃;(C)通式为X1nM(OR¹)m-n[其中X¹代表氢原子、卤素原子或有1至20个碳原子的烃基]的化合物、和 (C) 由通式 X1nM(OR¹)m-n 代表的化合物[其中 X¹ 代表氢原子、卤素原子或具有 1 至 20 个碳原子的烃基,M 代表硼、碳、铝、硅或磷原子、R¹代表具有 1 至 20 个碳原子的烃基,m 代表 M 的化合价,且 m > n ≧ O]接触 (D) 含卤素的醇,然后接触 (E) 供电子化合物和 (F) 钛化合物,从而形成含钛固体物质、并使所述含钛固体物质在 (G) 有机铝化合物的存在下接触 (H) 烯烃,从而使所述含钛固体物质以 0.1 至 100 克每克所述含钛固体物质。
