Abstract

열가소성수지의 제조방법에 관한 것으로서, 더욱 상세하게는 고무질 탄성체와 공중합 가능한 비닐계 단량체의 그라프트 공중합시 특정의 다른 입자경을 갖는 두종의 고무를 사용하고 입경의 분자량 분포가 작은 괴상-현탁중합으로 제조된 산(SAN) 공중합체를 사용하므로서 시트압출성이 우수하고 온도변화에 따른 기계적 물성의 변화가 적으며 내약품성이 양호하여 우레탄 발포시 깨짐발생이 없고 진공성형이 우수한 열가소성수지를 제조하는 새로운 방법에 관한 것이다.The present invention relates to a method for preparing a thermoplastic resin, and more particularly, to manufacture graft copolymerization of a vinyl monomer copolymerizable with a rubbery elastomer using two kinds of rubbers having specific different particle diameters and to prepare a bulk-suspension polymerization having a small molecular weight distribution of particle diameters. New method for producing thermoplastic resins with excellent vacuum molding due to excellent sheet extrudability, little change of mechanical properties with temperature change and good chemical resistance by using acidic acid (SAN) copolymer. It is about.
