Abstract

본 발명은 α-알킬스틸렌의 함량이 높고 내열성이 향상된 아크릴로니트릴-부타디엔-스티렌(이하ABS라 칭함)수지의 제조방법에 관한 것이다.
본 발명은 α-알킬스티렌 68∼85중량%, 아크릴로니트릴 15∼32중량%로 구성되는 혼합물을 라디칼 개시재의 존재 하에서 유화중합 함에 있어서, α-알킬스티렌과 아크릴로니트릴을 3단계로 분리하여 투입시키는 것을 특징으로 하며, 제1단계에 투입되는 α-알킬스티렌과 아크릴로니트릴의 량이 각각 5∼29중량%와 1∼25중량%이고, 제2단계에서 투입되는 α-알킬스티렌과 아크릴로니트릴의 량이 각각 40∼80중량%이며, 제2단계 투입시기는 제1단계에서 투입된 아크릴로니트릴의 40∼80중량%가 소모되는 시점이다.
