Abstract

PURPOSE:To decrease a content of titanium in a catalyst and remarkably increase the polymerizing activity per unit titanium, by bringing titanium tetrachloride into contact with a co-pulverized mixture of diethoxymagnesium, calcium chloride and a silicon compound in a specified manner. CONSTITUTION:This component of a solid catalyst for polymerization of olefins is prepared by the following procedures. (1) Diethoxymagnesium (a), calcium chloride (b) and a silicon compound (c) of a general formula Si(OR)4 (wherein R is alkyl or aryl radical) are co-pulverized. (2) The product is suspended in a liquid aromatic hydrocarbon (d) at room temperature and then brought into contact with titanium tetrachloride (e). (3) The product is further brought into contact with titanium tetrachloride (e). A diester (f) of an aromatic dicarboxylic acid is added during the processes of the aforementioned suspending and/or contacting, and the ratio of component b to component a is 1-2 by weight.
