Abstract

PURPOSE: To improve stereoregularity of polypropylene, by using a highly active catalyst obtained by a combination of glycol ether and a modified component prepared by treating titanium thicloride with an olefin and an aluminum alkyl compound.
CONSTITUTION: Propylene is polymerized by using a catalyst consisting of a combination of A) a modified component obtained by a contact reaction of titanium trichloride with an olefin and an aluminum alkyl compound shown the formula AlR2X (R is alkyl; X is halogen atom), and B) a glycol ether (e.g., ethylene glycol munomethyl ether) shown by the formula R(OCnH2n)mOH (R is alkyl; n is 1W6; m is 1W5).
EFFECT: A stereoregular polymer can be obtained stably with little dispersions.
