The present invention provides a chlorinated vinyl chloride-based resin that has poor thermal decomposition properties, is excellent in continuous productivity during molding, and can achieve both workability and non-uniformity prevention properties of a molded article. The present invention measures the free-induced decay curve of spin-spin relaxation of 1 H at 150° C. by the Solid Echo method using pulse NMR , A 150 component, B 150 in descending order of relaxation time by the least squares method. component, and chlorinated vinyl chloride C separation waveform with three curves derived from three components of the 150 component, C component ratio of the 150 component obtained by [C 150 component / (a 150 component + B 150 component + C 150 component)] is less than 8.0% it is resin |
