Abstract

PURPOSE: To improve the copolymerization rate of ethylene and propylene sharply and increase the productivity, by polymerizing propylene in the presence of a catalyst consisting of titanium trichloride and an organoaluminum compound, and by copolymerizing the polymer thus obtained with etylene or ethylene and propylene.
