Abstract
Ternary PC/ABS blends were prepared by direct melt blending of polycarbonate(PC). SAN and g-ABS copolymer of which the ABS resin is composed. As the content of PC was varied while maintaining SAN/g-ABS weight ratio of 85/15 (ABS-1) and 70/30 (ABS-2), the most distinguished improvement was observed in the notched Izod impact strength which was much higher than binary PC/ABS blend and even higher than pure PC polymer at optimum PC content of 60%. The effect of PC content and homogenous distribution of g-ABS by ternary PC/ABS blending on the other properties such as ultimate tensile strength, elongation and melt rheology are discussed case by case.

Polycarbonate(PC) 및 ABS 수지의 구성 성분인 SAN 및 g-ABS 공중합체를 용융 블렌딩하여, 3원 고분자 합금 형태의 PC/ABS 블렌드를 제조하고 열적, 기계적 및 점도 성질을 조사하였다. SAN/g-ABS의 조성비를 85/15 및 70/30의 일정 비율로 유지하면서 PC의 함량을 변화시켰을 때, 가장 뛰어난 성질은 충격강도의 증가로서 PC가 60%인 경우는 2원 PC/ABS 합금보다는 물론 순수한 PC보다 높은 충격강도를 나타내었다. 이외에도 PC함량의 변화 및 3원 합금법에 따른 g-ABS의 균일한 분포가 인장 강도, 연신율 및 점도 거동에 미치는 영향을 고찰하였다.
