Abstract

The reactive modification of acrylonitrile-butadiene-styrene (ABS) with glycidyl methacrylate (GMA) was conducted in a melt mixing process. The reaction characteristics of GMA with ABS were investigated for various processing conditions and compositions of the materials in the presence of dicumyl peroxide as an initiator of the radical reaction. The graft ratio of GMA increased as the concentration of GMA increased and showed the maximum value in the given range of mixing time. The influence of the RPM of the mixer on the graft rate was not significant, and the graft ratio decreased as the processing temperature increased. The complex viscosity and storage modulus of the modified ABS increased significantly when the graft ratio was highest. GMA-grafted ABS (ABS-g-GMA) was blended with poly(lactic acid) (PLA) to assess the enhancement of the compatibility in the blend. Compared to the blend of ABS/PLA, the ABS-g-GMA/PLA blend showed a remarkable reduction in the size of the domain with the increase of complex viscosity.


용융혼련에서 acrylonitrile-butadiene-styrene(ABS) 수지와 glycidyl methacrylate(GMA)의 그래프트 반응 특성을 조사하였다. 라디칼 반응의 개시제로서 dicumyl peroxide(DCP)을 사용하였고 GMA 농도, 믹서의 RPM, 혼련 시간, 그리고 가공 온도를 변화시켰다. GMA의 그래프트율은 GMA의 농도에 따라 증가하였고 주어진 혼련 시간범위에서 최대값을 나타내었다. 믹서의 RPM이 그래프트율에 미치는 영향은 크지 않았으며 가공 온도가 증가할수록 그래프트율은 감소되었다. 개질된 ABS의 복소점도와 저장 모듈러스는 그래프트율이 가장 높은 값을 가질 때 증가되었다. GMA가 그래프트된 ABS와 poly(lactic acid)(PLA)의 블렌드를 제조하고 ABS/PLA블렌드의 형태학과 전단점도를 비교하였다. 개질된 ABS가 도입된 블렌드에서는 PLA의 말단기와 GMA가 반응하여 단순 블렌드 대비 현저한 분산상의 크기 감소를 나타내었고 전단점도도 상승하였다.
