Abstract
본 발명은 아크릴로니트릴 스티렌 공중합 수지의 황변 현상 개선을 위한 제조방법에 관한 것으로, 연속 공정에서 아크릴로니트릴 25~40중량부, 스티렌 75~60중량부 용매로서는 톨루엔을 26~28중량부를 혼합한 원료액을 평균 반응 시간이 2시간이 되도록 투입량을 유지하고 반응온도를 150~155℃를 유지하는 것을 특징으로 한다.The present invention relates to a manufacturing method for improving yellowing of acrylonitrile styrene copolymer resin, in which 25 to 40 parts by weight of acrylonitrile and 75 to 60 parts by weight of styrene in a continuous process are mixed with 26 to 28 parts by weight of toluene. It is characterized by maintaining the input amount of the raw material solution so that the average reaction time is 2 hours and the reaction temperature is 150 ~ 155 ℃.
