Abstract: 본 발명은 발포성 스티렌 수지 입자를 제조하기 위한 현탁중합법에 있어서 고체미분말, 전해질, 음이온계 계면흡착성 고분자, 및 수용성 과산화염을 조합한 현탁안정제를 사용하려, 고수득율의 좁은 입자 크기 분포를 갖는 발포성 스티렌 수지입자의 제조방법에 관한 것이다. 이러한 과산화염을 포함한 신규의 현탁중합법은 값싼 분산제를 소량 사용함으로써 상업적 효율이 뛰어나고, 중합과정에서 입자간 합일이 일어나지 않기 때문에 입자내부의 부착수분이 없어서 균일한 발포성 스티렌수지 입자를 고수율로 얻을 수 있다. 본 발명의 방법에 따라 제조된 발포체는 상업성이 뛰어나 발포성 스티렌 수지 제조에 이용가치가 높다.
