Abstract

PURPOSE: To produce a highly stereoregular polyolefin in high activity, by polymerizing an olefin with the aid of a catalyst comprising a specified activated titanium catalytic component, an electron-donating compound and an organometallic compound.
CONSTITUTION: An olefin is polymerized with the aid of a catalyst comprising (A) a solid reaction product prepared by reacting a magnesium dialkoxide of formulaIwith a halogen-containing alkoxy titanium compound of formula II, wherein R1 and R2 are each a 1W20C alkyl, cycloalkyl, aryl or aralkyl, X is a halogen and n is in the range of 0<n<4, an electron-donating compound (e.g., ethyl benzoate) and a halogenating agent (e.g., a compound of formula III, IV, V or VI, wherein R3W6 are each a 1W10C alkyl, X2W4 are each Cl or Br, m, l and j are each 0W4 and k is 0W3), (B) an electron-donating compound and (C) an organometallic compound containing a metal selected from the class consisting of metals of GroupsIand II of the periodic table.
