Abstract

Polymer blends containing polypropylene (PP) with compatibilizers were prepared using twin screw extruder. Physical properties were investigated using universal test machine (UTM) and Izod impact tester. In the PP/acrylonitrilebutadiene-styrene (ABS) blends, mechanical strength was increased with the addition of PP-g-styrene acryloritrile (PP-g-SAN) compatibilizer, and the ductility was increased with the addition of ethylene-ethyl acrylate-maleic anhydride (E-EAMAH-g-SAN) compatibilizer. For the PP/ABS/ polycarbonate (PC)/Nylon-6,6 blends, impact strength was increased with the addition of ethylene glycidylmethacrylate (E-GMA compatibilizer) up to 0.5 phr. In the case of the PP/ABS/PC/Nylon-6,6/poly(methyl methacrylate) (PMMA)/poly(oxymethylene) (POM)/poly(vinyl acetate) (PVC)/poly(butylene terephthalate) (PBT) blends, mechanical properties were increased by the complex compatibilizing effects of PP-g-SAN, E-EA-MAH-g-SAN and E-GMA, respectively.

폴리프로필렌(PP)을 포함한 고분자 블렌드에 상용화제를 첨가하여 이축압출기를 통해 시편을 제조하였으며, universal testing machine(UTM), lzod 충격 시험기를 사용하여 물성을 측정하였다. PP/acrylonitrile-butadiene-styrene(ABS) 블렌드의 경우, PP-g-styrene acrylonitrile(PP-g-SAN) 상용화제의 첨가에 의해 기계적 물성이 증가하였으며, ethylene-ethyl acrylate-maleic anhydride(E-EA-MAH-g-SAN) 상용화제의 첨가에 의해서 연성이 증가하는 결과를 나타내었다. PP/ABS/polycarbonate(PC)/Nylon-6,6 블렌드의 경우, ethylene glycidylmethacrylate(E-GMA) 상용화제를 0.5 phr 첨가함에 따라 충격강도가 증가하는 결과를 나타내었다. PP/ABS/PC/Nylon-6,6/poly(methyl methacrylate)(PMMA)/poly(oxymethylene)(POM)/poly(vinyl acetate)(PVC)/poly(butylenes terephthalate)(PBT) 블렌드에서 PP-g-SAN 같은 물리적 상용화제와 E-GMA 와 E-EA-MAH-g-SAN 같은 반응상용화제의 복합적인 작용으로 인해 블렌드의 기계적 물성이 증가된 결과를 나타내었다.
