Abstract

PURPOSE: To prepare the title polymer having high bulk density, without eliminating the catalyst residue, while preventing the deposition to the walls of the reactor, by the use of a highly active catalyst containing a solid component obtained by contacting a specific carrier with a titanium compound.
CONSTITUTION: The objective polymer can be prepared by the use of a catalyst comprising (A) a solid component obtained by reacting (a) a tetra-valent titanium compound having one or more halogen atoms with (b) a reaction product insoluble to hydrocarbon solvents, obtained by the reaction of (1) an inorganic oxide such as SiO2, Al2O3, etc., (2) an aluminum halide, (3) an organo-silicone compound having an Si-O bond, and (4) magnesium alcoholate, and (B) an organo-aluminum compound.
EFFECT: A copolymer of ethylene and α-olefin has unform short-branch distribution. and high environmental stress cracking resistance.
