Abstract
PURPOSE: To produce a highly stereoregular polyolefin in high activity, by polymerizing an α-olefin with a catalyst comprising a specified activated titanium catalytic component and a specified organoaluminum compound.
CONSTITUTION: A polyolefin having high polymerization activity, high stereoregularity and a high bulk density is produced by polymerizing an α-olefin with the aid of a catalyst comprising (A) a product obtained by reacting a titanium tetrahalide with an alkoxide of formulaIor II, wherein R1 and R2 are each a 1W20C alkyl, cycloalkyl, aryl or aralkyl, and reacting the resulting solid substance with a halogen-containing titanium compound of formula III, wherein R3 is a 1W20C alkyl, cycloalkyl, aryl or aralkyl, X is a halogen and n is in the range of 0≤n<4, in the presence of an electron-donating compound (e.g., ethyl benzoate) and (B) an organoaluminum compound (e.g., trimethylaluminum).
