Abstract

PURPOSE: To obtain the titled polymer having a high stereoregularity, by using a catalyst containing (A) a solid component consisting of a compound having Mg-O bonds, phosphorus pentachloride, etc., an alkoxyl compound, an unsaturated carboxylic acid and a Ti compound and (B) an organoaluminum compound.
CONSTITUTION: An olefin, e.g. propylene, is polymerized in the presence of a catalyst consisting of (A) a solid component obtained by combining (a) a magnesium compound having Mg-O bonds, e.g. magnesium oxide, with (b) phosphorus pentachloride or trichloride, (c) a compound having an alkoxyl group, e.g. triethyoxyboron, (d) an α,β-unsaturated carboxylic acid or a metallic salt or acid halide thereof, e.g. benzoyl chloride, and (e) a titanium compound, e.g. titanium tetrachloride, and (B) an organoaluminum compound, e.g. triethylaluminum.
