Abstract

PURPOSE: To prepare a highly stereoregular polyolefin in high yield, by polymerizing an ethylenic unsaturated monomer in the presence of a catalyst system consisting of a plurality of specific solid products, an organometallic compound, etc..
CONSTITUTION: An ethylenic unsaturated monomer is polymerized in the presence of a catalyst system comprising (A) a solid product prepared by contacting (a1) a magnesium halide and/or (a2) a solid reaction product of a magnesium compound having hydroxyl groups bonded to magnesium, with an organoaluminum compound RnAlX3-n (R is 1W20C hydrocarbon; X is halogen; 0<n≤1.5), with (b) halides of iron, niobium, antimony and/or bismuth, (c) an electron donor (pref. armatic carboxylic acid esters), and (d) a titanium halide, and (B) an organometallic compound of IWIII groups metal in the periodic table and/or its addition or reaction product with an electron donor.
