摘要： The present invention provides a chlorinated polyvinyl chloride that enables excellent continuous productivity in molding and that enables a molded article to have both processability and unevenness-preventing properties. Provided is a chlorinated polyvinyl chloride having an endothermic peak start temperature (L) and an endothermic peak end temperature (H) that satisfy the following expression (1) in endothermic peak measurement using a differential scanning calorimeter (DSC): 41° C.≤H−L≤98° C. (1).
