Abstract

PURPOSE: To prevent the closing of a catalyst feed pipe and the formation of a bulk polymer, etc., by adding a catalyst suspension consisting of titanium trichloride, an organoaluminum compound, and an inert organic solvent to a propylene polymerizing system at a specific temperature.
CONSTITUTION: A) A catalyst suspension consisting of titanium trichloride, an organoaluminum compound(preferably diethylaluminum monochloride), and an inert organic solvent, e.g., a saturated hydrocarbon or B) a polymer suspension wherein an olefin is polymerized previously in the presence of the suspension B) is cooled to 10W-50°C. The cooled suspension is added to a propylene polymerizing system to undergo polymerization.
EFFECT: Not accompanied by the formation of a bulk or a string polymer.
