Abstract

본 발명은 열가소성 수지분말의 제조방법에 관한 것이다.The present invention relates to a method for producing a thermoplastic resin powder.

본 발명은 충격 및 외관이 우수한 열가소성 수지분말을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a thermoplastic resin powder having excellent impact and appearance.

본 발명은 고무중합체, 불포화니트릴 단량체, 비닐방향족 화합물 단량체를 유화중합 방법에 의한 제1공정, 제2공정, 후처리공정을 통하여 얻는 열가소성 수지의 제조방법에 있어서, 제1, 2공정을 통하여 얻어진 열가소성수지 라텍스에 후처리 공정을 행하기 전에 이온교환수를 투입하여 응고시키는 것을 특징으로 한다.The present invention is a method for producing a thermoplastic resin obtained by the first step, the second step, and the post-treatment step of the rubber polymer, the unsaturated nitrile monomer, and the vinyl aromatic compound monomer by the emulsion polymerization method, obtained through the first and second steps. It is characterized in that the ion-exchange water is added and solidified before the post-treatment step is performed on the thermoplastic latex.
