Abstract

PURPOSE: To prepare a highly crystalline polymer in high catalyst efficiency, by preliminarily polymerizing an olefin under a specific condition in the presence of a catalyst system containing titanium trichloride and an organoaluminum compound, and subsequently carrying out the polymerization.
CONSTITUTION: An olefin, e.g. propylene, etc., is preliminarily polymerized in the presence of a catalyst system comprising (A) titanium trichloride having a particle size of 10W50μ and a specific surface area of ≥80m2/g, and (B) an organoaluminum compound, e.g. diethylaluminum monochloride, etc., to attain the polymerization rate of 4W70 g.polymer/g.titanium trichloride/hr and the polymer yield of 3W100g.polymer/g.titanium trichloride. Subsequently, an olefin, e.g. propylene, ethylene, etc., is (co)polymerized in the presence of the catalyst and the prepolymer to give the desired polymer.
EFFECT: The amount of the amorphous polymer is extremely reduced.
