Poly-butylene-terephalate(PBT) can be impact modified by blending with ABS material. The effects of the type of compatibilizer and ABS content on the mechanical properties of PBT/ABS blend were examined in this study. EVA-g-GMA and three type of polycarbonates were used as the compatibilizer. As the GMA content in EVA-g-GMA was increased, the tensile strength of PBT/ABS blend increased and the impact strength of it decreased. With increasing the EVA-g-GMA content in PBT/ABS blend, the tensile strength and impact strength decreased. With PC compatibilizer, the tensile strength of PBT/ABS blend decreased as the ABS content increased. However, the maximum impact strength was observed in 20~30% ABS content range.

Poly-butylene-terephalate(PBT) can be impact-modified by blending with ABS material. The effects of compatibilizers and ABS content on the mechanical properties of PBT/ABS blend were examined in this study. EPDM-g-GMA and polycarbonate(PC) were used as a compatibilizer. As the GMA content in EPDM-g-GMA increased, the tensile strength of PBT/ABS blend increased and the impact strength decreased. With increasing the EPDM-g-GMA content in PBT/ABS blend, the tensile strength and impact strength decreased. With PC compatibilizer, the particle size of ABS in PBT/ABS blend became smaller than that of the blend without compatibilizer and the particles were more evenly dispersed in matrix. The maximum impact strength of the PBT/ABS blend was observed in the range of 20~30% ABS content.

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.
