초록

본 연구에서는 PPS와 ABS의 물성을 상호보완하며, 두 성분간의 상용성을 향상시키기 위해 반응압출법을 이용하여 maleic anhydride(MAH)를 ABS에 치환시켜 MABS를 제조하였으며, ABS의 화학적 개질이 블렌드의 기계적 및 동력학적 물성에 미치는 영향을 관찰하였다. 동력학적 특성 분석을 통하여서는 PPS/MABS 블렌드가 거의 전조성 영역에서 단일 유리전이온도를 가짐을 확인하였다. 블렌드의 기계적 성질은, 상용화제를 포함하고 있는 블렌드가 더욱 강한 인장강도, 굴곡강도, 충격강도 등을 나타냄을 확인하였다. 이는 상용화제의 도입으로 인해 분산상과 매트릭스 사이의 계면장력이 낮아져 분산상의 크기가 작아지며 계면간의 상호작용이 증진되어 물성이 향상되었기 때문이다.

In this study, the PPS/ABS blend system was investigated in order to identify the relationship between the incorporation of compatabilizing moieties and the mechanical properties. ABS resin was chemically modified by the incorporation of maleic anhydride using reactive extrusion method to yield MABS resin, and PPS/MABS blend was prepared by a twin screw extruder. Single glass transition behavior was observed in the various compositions of PPS/MABS blend by dyanmic mechanical analysis study. Upon the examination of the mechanical properties, the PPS/MABS blend exhibited an enhanced tensile, flexural and impact strength, which might be due to the better chemical compatibilization to result in the reduced interfacial tension between each components.

Keywords:PPS/ABS blend;mechanical;compatibilization
