Abstract
본 발명은 투명성이 우수하며 구조가 복잡하고 얇은 성형물의 사출성형에 적합한 이형성이 우수한 투명한 스티렌계 열기소성 수지의 제조방법을 제공하기 위한 것으로서, 중량평균 분자량이 18만 내지 33만인 스티렌계 열가소성 수지를 제조함에 있어서, 모노비닐 방향족화합물에 징크-스테아레이트, 메틸페닐실리콘오일을 투입하여 열 또는 개시제에 의한 괴상연속 중합방법에 의하여 제조함을 특징으로 한다.The present invention provides a method for producing a transparent styrene-based thermoplastic resin having excellent transparency and excellent mold releasability, which is suitable for injection molding of a thin molded article, which is excellent in transparency and has a styrene-based thermoplastic resin having a weight average molecular weight of 180,000 to 330,000 In the preparation, it is characterized in that zinc-stearate and methylphenyl silicone oil are added to a monovinylaromatic compound, followed by bulk continuous polymerization using heat or an initiator.
