Abstract
본 발명은 염화비닐 단량체를 수매체중에서 현탁중합하여 폴리염화비닐 수지를 제조하는 방법에 관한 것으로, 염화비닐 단량체에 중합 개시제 및 유용성 부원료를 중합 개시전에 투입하고, 중합 개시후 중합 전환율이 5 내지 15% 진행되었을 때 분산제를 투입하는 방법을 사용함으로써 가공성이 우수한, 특히 성형 후 제품의 표면 상태가 우수한 폴리염화비닐 수지를 얻을 수 있다.The present invention relates to a method for producing a polyvinyl chloride resin by suspending and polymerizing a vinyl chloride monomer in an aqueous medium, wherein a polymerization initiator and an oil-soluble auxiliary material are added to a vinyl chloride monomer before the start of polymerization, and the polymerization conversion rate is 5 to 15 after the start of polymerization. By using the method of injecting a dispersant when the% has been advanced, a polyvinyl chloride resin having excellent processability, in particular, having excellent surface state of the product after molding can be obtained.
