Abstract

본 발명은 내충격성 및 저온 충격성을 가지는 내후성 열가소성 수지의 제조방법에 관한 것으로서, 더욱 상세하게는 탄소수 1~12개의 알킬아크릴레이트와 공액디엔계 고무로 이루어진 공중합체와, 공액디엔계 고무와 방향족 비닐화합물로 이루어진 또다른 공중합체를 혼합사용함으로써 저온 충격성을 향상시키고 그라프트 중합을 용이하게 하는 내후성 열가소성 수지의 새로운 제조방법에 관한 것이다.The present invention relates to a method for producing a weather resistant thermoplastic resin having impact resistance and low temperature impact, and more particularly, a copolymer consisting of alkyl acrylate having 1 to 12 carbon atoms and conjugated diene rubber, conjugated diene rubber and aromatic vinyl. The present invention relates to a new method for producing a weather resistant thermoplastic resin by improving the low temperature impact resistance and facilitating graft polymerization by mixing and using another copolymer made of a compound.
