Catalytic component and catalyst for polymerizing olefins

Abstract

Abstract PURPOSE:The titled catalyst keeping activity, providing an odorless high stereoregular polymer, obtained by blending a reaction product of a specific Mg compound, an aromatic dicarboxylic acid ester, a halogenated hydrocarbon and a Ti compound with an Si compound and an organoaluminum compound. CONSTITUTION:(A) A component obtained by reacting (i) a magnesium salt of fatty acid with (ii) a dialkoxy magnesium, (iii) an aromatic dicarboxylic acid mono- or diester, (iv) a halogenated hydrocarbon and (v) a titanium halide shown by the formula TiX4 (X is halogen) is blended with (B) a silicon compound shown by the formula SiRm(OR')4-m (R is H, alkyl, or aryl; R' is alkyl, or aryl; 0<=m<=4), and (C) an organoaluminum compound, to give the desired catalyst.
