Abstract

PURPOSE: To reduce the ratio of amorphous polymer by the use of a catalyst activated prior to polymerization which is prepared by letting a catalyst dispersion, obtained by mixing a δ-type titanium trichloride composition with an alkyl aluminum chloride in an insoluble solvent, absorb propylene.
