예를 들어, 특허문헌 1 및 특허문헌 2에 아크릴로니트릴-부타디엔-스티렌 공중합체(이하, ABS수지라고도 함)가 기재되어있다. 또한, 부타디엔의 함유량이 높은 ABS수지는 우수한 기계적 성질, 내화학약품성 및 치수 안정성 등의 특성을 가지므로, 전기제품이나 자동차용품 등 다양한 영역에 사용되고 있다. 이러한 영역의 제품에 대한 성능 요구가 높아짐에 따라, 부타디엔의 함유량이 높은 ABS수지의 특성 향상에 관한 연구도 이루어지고 있다.For example, Patent Document 1 and Patent Document 2 describe an acrylonitrile-butadiene-styrene copolymer (hereinafter also referred to as ABS resin). In addition, ABS resin with a high content of butadiene has excellent mechanical properties, chemical resistance and dimensional stability, and thus is used in various fields such as electric products and automobile products. As the performance requirements for products in this area increase, research on improving the properties of ABS resins with high butadiene content is also being conducted.
부타디엔의 함유량이 높은 ABS수지를 개질하는 방법 중 하나는, 아크릴로니트릴-스티렌 공중합체를 부타디엔의 함유량이 높은 아크릴로니트릴-부타디엔-스티렌 공중합체에 첨가시키는 것이다. 그러나, 아크릴로니트릴-부타디엔-스티렌 공중합체 내의 부타디엔의 함유량이 높아서, 아크릴로니트릴-부타디엔-스티렌 공중합체와 아크릴로니트릴-스티렌 공중합체 간의 상용성(compatibility)이 나빠서, ABS수지의 특성을 효과적으로 향상시키는 것이 어렵다.One of the methods of modifying the ABS resin having a high butadiene content is to add an acrylonitrile-styrene copolymer to the acrylonitrile-butadiene-styrene copolymer having a high butadiene content. However, since the content of butadiene in the acrylonitrile-butadiene-styrene copolymer is high, compatibility between the acrylonitrile-butadiene-styrene copolymer and the acrylonitrile-styrene copolymer is poor, and the properties of the ABS resin are effectively improved It is difficult to improve.

표 1의 데이터를 통해, 아크릴로니트릴-부타디엔-스티렌 공중합체의 사용량 및 아크릴로니트릴-스티렌 공중합체의 사용량이 동일한 실시예 및 비교예를 비교하면, 실시예 1, 2, 5 내지 8의 내충격강도가 비교예 1의 내충격강도보다 높고, 실시예 3의 내충격강도가 비교예 2의 내충격강도보다 높으며, 실시예 4의 내충격강도가 비교예 3의 내충격강도보다 높은 것을 알 수 있다.Through the data in Table 1, when comparing Examples and Comparative Examples in which the amount of the acrylonitrile-butadiene-styrene copolymer and the amount of the acrylonitrile-styrene copolymer are the same, the impact resistance of Examples 1, 2, 5 to 8 It can be seen that the strength is higher than the impact strength of Comparative Example 1, the impact strength of Example 3 is higher than the impact strength of Comparative Example 2, and the impact strength of Example 4 is higher than the impact strength of Comparative Example 3.
즉, 화학식 I로 표시되는 이소시아누레이트계 상용화제를 포함하는 스티렌 공중합체 함유 조성물에 의한 성형품의 내충격강도는 화학식 I로 표시되는 이소시아누레이트계 상용화제를 포함하지 않는 스티렌 공중합체 함유 조성물에 의한 성형품의 내충격강도보다 높은 것을 알 수 있다.That is, the impact strength of the molded article by the composition containing the styrene copolymer including the isocyanurate-based compatibilizer represented by Formula I is the styrene copolymer-containing composition without the isocyanurate-based compatibilizer represented by Formula I. It can be seen that the impact strength of the molded product by
따라서, 화학식 I로 표시되는 이소시아누레이트계 상용화제를 포함함으로써, 아크릴로니트릴-부타디엔-스티렌 공중합체와 아크릴로니트릴-스티렌 공중합체 간의 상용성이 확실히 증가하므로, 아크릴로니트릴-부타디엔-스티렌 공중합체와 아크릴로니트릴-스티렌 공중합체를 보다 균일하게 혼합할 수 있어서, 성형품의 내충격강도가 종래보다 높아진다.Therefore, by including the isocyanurate-based compatibilizer represented by the formula (I), the compatibility between the acrylonitrile-butadiene-styrene copolymer and the acrylonitrile-styrene copolymer is definitely increased, so acrylonitrile-butadiene-styrene Since the copolymer and the acrylonitrile-styrene copolymer can be mixed more uniformly, the impact strength of the molded article is higher than that of the prior art.
