Abstract

PURPOSE: To prepare the title copolymer having high impact strength, rigidity and heat resistance, by polymerizing propylene in the presence of titanium trichloride and an organo-aluminum compound, and then carrying out the random copolymerization of propylene and ethylene in the presence of the above polymer.
CONSTITUTION: Propylene (which may contain a small amount of ehylene) is polymerized in liquid state, in the absence of an inert solvent, and then randomly copolymerized with propylene and ethylene in liquid propylene or in gaseous phase. The polymerization is carried out in the presence of a catalyst system comprising (A) a solid TiCl3 catalyst obtained by reducing TiCl4 with an organo-aluminum compound, and activating the product, (B) an organo-aluminum compound of formula (R is 1W8C straight chain alkyl, etc.; Y is halogen, etc.; l is 2W3), and if necessary, (C) an agent for improving the stereoregularity. The weight ratio of the polymer to the TiCl3 catalyst is ≥8000/1.
