Polyvinylchloride resin(I), useful as filler, was prepd. by suspension polymerization of polyaryl compd. 0.01-2% and low molecular propylene polymer 0.01-5% (basic on the wt. of all monomer) mixt.. Thus, methocel K-35 400 gal, diarylphthalate 15 lbs, propylenetetramer 40 lbs, and sulfosuccinate as emulsifing agent 10 lbs were mixed in the deionized water. The mixt. was stirred for 10 min, 10 Lbs of azobisisobutylonitrile as catalyst was added at 49.4≦̸C, 15-20 in Hg, and then 10000 Lbs of vinylchloride monomer was added, and then stirred at 71≦̸C to give I.
