Zusammenfassung:	The present invention relates to a method for manufacturing a chlorinated polyvinyl chloride resin. Provide is a method which optimizes all of a polymerization step of manufacturing a vinyl chloride-based polymer; a step of chlorinating the vinyl chloride-based polymer; and a step of neutralizing the same, such that a floating phenomenon of the resin and a cavitation phenomenon in a pump are eliminated in the manufacturing of the chlorinated polyvinyl chloride resin, thereby manufacturing a chlorinated polyvinyl chloride resin excellent in all properties, such as a whiteness index, bulk density, porosity, etc. with high process efficiency while achieving an improvement in productivity. 본 발명은 염소화 폴리염화비닐 수지의 제조 방법에 관한 것으로, 염화비닐계 중합체를 제조하는 중합 공정, 염화비닐계 중합체를 염소화하는 공정, 및 이를 중화하는 공정을 모두 최적화함으로써, 염소화 폴리염화비닐 수지 제조시 수지의 부유 현상, 펌프에서 캐비테이션 현상을 제거하여 생산성을 향상시키면서 백색도, 벌크 밀도, 기공도 등의 물성도 모두 우수한 염소화 폴리염화비닐 수지를 높은 공정 효율로 제조하는 방법이 제공된다.
