CHLORINATED VINYL CHLORIDE RESIN

摘要

PROBLEM TO BE SOLVED: To provide a chlorinated vinyl chloride resin having excellent heat resistance and therformability. SOLUTION: There is provided a chlorinated vinyl chloride resin prepared by chlorinating a vinyl chloride resin and having an average chlorine content of 68-72 wt.% and a melt viscosity (at 200 deg.C) of 8×10<4> to 2×10<4> P. It is desirable that the average-degree of polymerization of the vinyl chloride resin is 400-600, and the chlorinated vinyl chloride resin is desirable for calendering.
