Abstract

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.
