Abstract

현탁중합용분산안정제(A)의 존재하에서 비닐계화합물의 현탁중합을 행하는데 있어서 환류응축기부착의 중합탱크를 사용해서 중합전화율 30~90%의 시점에서 비닐계화합물 100중량부에 대해 가수분해도 85몰% 이하의 폴리비닐알코올계중합체(B) 0.001~0.5중량부를 첨가하는 것을 특징으로 하는 비닐계수지의 제조방법.
본 발명에 의하면 생산성이 우수한 한류응축기부착 중합탱크를 사용하여 중합의 중간~후기에 발생하는 건조기포에 대한 소포효과가 우수하고 또한 충전비중이 높은 비닐계수지가 얻어지는 비닐계수지의 제조방법이 제공된다.
