Abstract

PURPOSE: To (co)polymerize propylene (P) or P with other olefins in high yields in two steps, by using a specific catalyst under specified condition.
CONSTITUTION: A polymer composition, obtained by preliminarily polymerizing propylene (P) or P with other defins in the presence of a catalyst consisting of one mole of a highly active TiCl3 to give a polypropylene yield ≥ 2,000g./g.TiCl3. hr and 0.2W4 moles of a dialkylaluminum monochloride (A) within the range of 1W 500g./g.TiCl3, is incorporated with the dialkylaluminum monochloride (B) so that the molar ratio of the total amount of (A) and (B) to TiCl3 may be 2W20:1. A≥2C alkyl ether is then added to the system at a molar ratio of the ether to TiCl3 of 0.1W2.0:1, and P or P and other olefins are polymerized at 50W100°C and 1W 100kg/cm2
