Abstract

Rubber powder (RP) was blended into biodegradable poly(butylene succinate) (PBS). The PBS/RP blends were prepared by an internal mixer with the ratios of 100/0, 90/10, 80/20, 70/30, 60/40 and 50/50 by weight. Thermal and mechanical properties of PBS/RP blends were investigated. The results of thermal stability showed that the melting temperature of PBS/RP blends tended to decrease with increasing rubber content until the ratio of 70/30 by weight. The degree of crystallinity of blends did not have relationship when the rubber powder was added. Moreover, tensile strength, Young’s modulus, elongation at break, hardness and impact strength were significantly related with rubber content.
