Abstract
PURPOSE:To provide a catalyst acting in high activity, thus capable of giving ordered highly stereoregular polymers when applied to olefin polymerization, consisting of a specific solid catalytic component, Si compound and organoaluminum compound. CONSTITUTION:The objective catalyst consisting of (A) a solid catalytic component, (B) a silicon compound of formula (R is alkyl, vinyl, etc.; R' is alkyl; 0<=m<4), and (C) an organoaluminum compound. The component A can be prepared by the following processes: using magnesium halide, <=2pts.wt. per wt. of said magnesium halide, of tetralkoxytitanium, phthalic dihalide, aliphatic hydrocarbon liquid at -30-50 deg.C, and aliphatic alcohol liquid at -30-50 deg.C, a homogeneous solution is prepared followed by dripping this solution into TiCl4 kept at <=0 deg.C so as not to develop precipitate, and raising the temperature of the resultant solution while stirring, adding a phthalic diester to the system at >=80 deg.C while stirring, separating a solid product formed, and bringing TiCl4 into contact with said product in the presence of an aromatic (halogenated) hydrogen liquid at normal temperature.
