Abstract

본 발명은 임의로 고무 강화된 매트릭스 중합제(a)와 중량평균분자량이 1,000 내지 70,000이고 휘발물질 함량이 30% 이하이며 유리전이온도가 약 25℃ 이상인 리모넨 또는 알파 메틸스티렌 및 임의로 또 다른 공중합 가능한 비닐 방향족 단량체의 가소화량의 고형(실온 및 실내압에서)의 저분자량 중합체(b)를 포함하는 임의로 고무 강화된 모노비닐리덴 방향족 중합체 수지 조성물에 관한 것이다. 이러한 조성물은 놀랍게도 유동 특성이 향상되며 인성과 강성이 사실상 저하되지 않는다. 본 발명은 또한 본 발명의 조성물로부터 독립 기포 중합체 발포체를 제조하는 방법, 본 발명의 조성물 및 발포제를 함유하는 팽창성 또는 발포성 모노비닐리덴 방향족 중합체 조성물 및 생성된 중합체 발포체에 관한 것이다. 유리하게는, 본 발명의 발포체는 발포제로서 CO2만을 사용하여 제조할 수 있다.
