Abstract

본 발명은 열가소성 수지의 연속 제조방법에 관한 것으로서, 더욱 상세하게는 비닐계 수지 조성물을 유화중합시키되 수지 조성물 전량의 40-80중량%를 1차 유화중합하고 연속적으로 나머지 수지 조성물을 투입하여 재차 유화중합시킴으로써 분자량 분포가 일정하여 품질이 균일하고 내열성이 우수한 열가소성 수지를 제조하는 방법에 관한 것이다.The present invention relates to a continuous manufacturing method of a thermoplastic resin, and more specifically, to emulsify the vinyl-based resin composition, but to emulsify again by first emulsion-polymerizing 40-80% by weight of the total amount of the resin composition and continuously adding the remaining resin composition. The present invention relates to a method for producing a thermoplastic resin having a uniform molecular weight distribution by polymerization to have uniform quality and excellent heat resistance.
