Summary:PROBLEM TO BE SOLVED: To provide a new method for producing a highly syndiotactic vinyl chloride polymer having high crystallinity and excellent mechanical strength such as impact resistance without lowering the polymerization temperature. SOLUTION: A highly syndiotactic vinyl chloride polymer is produced by polymerizing a vinyl chloride monomer in the presence of an organic aluminum compound, titanium tetrachloride and a halogenated hydrocarbon.
