Abstract

본 발명은 열가소성 수지의 제조방법에 관한 것이다. 본 발명의 목적은 내열 ABS의 외관 및 물성을 결정하는데 있어 중요 부분을 차지하는 내열 SAN의 중합방법을 개량하여 내열성 SAN을 제공하는 것 및 이로부터 제조되는 최종제품인 내열 ABS 수지제품의 외관특성 특히 백색도를 개선시키는 것이다.The present invention relates to a method for producing a thermoplastic resin. An object of the present invention is to provide a heat-resistant SAN by improving the polymerization method of the heat-resistant SAN, which occupies an important part in determining the appearance and physical properties of the heat-resistant ABS, and the appearance characteristics, in particular, the whiteness of the heat-resistant ABS resin product that is manufactured therefrom. To improve.

본 발명은 알파-메틸스티렌 65-78중량부, 아크릴로니트릴 35-22중량부를 사용하여 현탁중합으로 내열 스티렌계 수지 공중합물을 제조하는데 있어서, 개시제로 10시간 반감기 온도가 80-100℃인 아조계 또는 과산화물계 개시제를 투입단량체 100중량부에 대하여 0.1-1.0부를 첨가하며, 10-30시간 라디칼 중합시키는 것을 특징으로 한다.The present invention is to prepare a heat-resistant styrene resin copolymer by suspension polymerization using 65-78 parts by weight of alpha-methylstyrene and 35-22 parts by weight of acrylonitrile. The crude or peroxide-based initiator is added 0.1-1.0 parts to 100 parts by weight of the input monomer, characterized in that the radical polymerization for 10-30 hours.
