    • A solid catalyst component for olefin polymerization catalysts prepared by suspending diethoxymagnesium (a) in an aromatic hydrocarbon (b) which is liquid at normal temperature and bringing the suspension into a first contact with titanium tetrachloride (c) to form a product and bringing it into a second contact with tianium tetrachloride (c) in such manner that a diester (d) of an aromatic dicarboxylic acid and calcium chloride (e) are allowed to coexist at any stage of the above suspending and/or contacts, the calcium chloride (e) being used in an amount of 1-2 grams per gram of the diethoxymagnesium (a). This solid catalyst component exhibits, when applied to the polymerization of olefins, a surprisingly enhanced polymerization activity per titanium atom and a high stereospecific performance and scarcely necessitates any deashing treatment, thus affording a great economical advantage.
    • 一种用于烯烃聚合催化剂的固体催化剂组分,其通过将二乙氧基镁(a)悬浮在常温下为液体的芳族烃(b)中并使悬浮液与四氯化钛(c)首次接触形成产物并使其进入 与四氯化钛(c)的第二次接触,使得芳族二羧酸和氯化钙(e)的二酯(d)在上述悬浮和/或接触的任何阶段共存,氯化钙(e )的用量为每克二乙氧基镁(a)1-2克。 当用于烯烃聚合时,该固体催化剂组分表现出惊人的增加的每个钛原子的聚合活性和高立体特异性性能,并且几乎不需要任何脱屑处理,从而提供了巨大的经济优势。

    • A solid catalyst component for olefin polymerization catalysts prepared by subjecting diethoxymagnesium (a), calcium chloride (b) and a silicon compound (c) of the general formula: Si(OR).sub.4 (wherein R is an alkyl or aryl group) together to a contact treatment in the presence of an organic solvent (d), suspending the treated composition in an aromatic hydrocarbon (e) which is liquid at normal temperature and bringing the suspension into a first contact with titanium tetrachloride (f) to form a product and bringing it to a second contact with titanium tetrachloride (f) in such manner that a diester (g) of an aromatic dicarboxylic acid is allowed to coexist at any stage of the above suspending and/or contacts with the exception of the contact treatment, the calcium chloride (b) being used in an amount of 1-2 g per gram of the diethoxymagnesium (a). This solid catalyst component exhibits, when applied to the polymerization of olefins, a surprisingly enhanced polymerization activity per titanium atom and a high stereospecific performance and scarcely necessitates any deashing treatment, thus affording a great economical advantage.
