Abstract

PURPOSE: To obtain efficiently a polyethylene having an adjusted molecular-weight distribution by a highly active catalyst, by using a specific solid component and an organoaluminum compound as the catalyst and adding an organic acid ester to a polymerization system.
CONSTITUTION: (A) A solid component (preferably a reaction product prepared by reacting a magnesium compound with TiCl4) having at least Ti, Mg, and chlorine, and (B) an organoaluminum compound preferably shown by the formula Rn 1AlX3-n (R1 is alkyl; X is H or halogen; n is 1W3) are used as a catalyst, and an organic acid ester (e.g., acetic ester, methacrylic ester, etc.) is added to a polymerization system. A ratio of component B to A is preferably 10W500 Al atoms in the component B per Ti atom in the component A, and the amount of the organic acid ester is such an amount to give 0.5W50 atoms per Ti atom in the component A.
