Abstract
The properties of poly(ethylene terephthalate) (PET)/maleic anhydride-grafted polypropylene (MAgPP)/poly(styrene-co-maleic anhydride) (PScMA) ternary blend were investigated. The ternary blend was immiscible based on the glass transition temperatures measured by dynamic mechanical analyzer (DMA). The degradation of MAgPP during melt mixing for 30 min at 280 degreesC did not affect the properties of the ternary blend. The interaction among the components was confirmed from the rheological properties, which was increased with the PScMA contents. In terms of the mechanical properties, it was observed to satisfy the mixture rule for a multiple system.

Poly(ethylene terephthalate) (PET)/maleic anhydride-grafted polypropylene (MAgPP)/poly(styrene-co-maleic anhydride) (PScMA) 삼상블렌드의 성질이 조사되었는데 dynamic mechanical analyzer(DMA)에 의해 측정된 유리전이 온도의 결과는 삼상블렌드가 비상용성임을 나타내었다. 280℃에서 30분간 용융혼합한 경우 MAgPP의 분해가 가장 심각했지만 삼상블렌드의 성질에는 크게 영향을 주지는 못했다. 구성 성분간의 상호작용이 유변학적 성질의 결과로 확인되었는데, 구성 성분 중 PScMA의 함량에 따라 상호작용도 증가하는 경향이 나타났다. 기계적 성질측면에서 보면 다성분계에서의 혼합법칙을 따르는 것이 관찰되었다.

Keywords: poly(ethylene terephthalate) (PET); maleic anhydride-grafted polypropylene (MAgPP); polystyrene-co-maleic anhydride (PScMA); ternary blend; compatibilizer
