中文摘要	three triblock copolymers of poly[styrene-b-(ethylene-co-butylene)-b-styrene] (sebs) of different molecular weights and one diblock copolymer of poly[styrene-b-(ethylene-co-butylene)] (seb) were used to compatibilize high density polyethylene/syndiotactic polystyrene (hdpe/sps, 80/20) blend. morphology observation showed that phase size of the dispersed sps particles was significantly reduced on addition of all the four copolymers and the interfacial adhesion between the two phases was dramatically enhanced. tensile strength of the blends increased at lower copolymer content but decreased with increasing copolymer content. the elongation at break of the blends improved and sharply increased with increments of the copolymers. drop in modulus of the blend was observed on addition of the rubbery copolymers. the mechanical performance of the modified blends is strikingly dependent not only on the interfacial activity of the copolymers but also on the mechanical properties of the copolymers, particularly at the high copolymer concentration. addition of compatibilizers to hdpe/sps blend resulted in a significant reduction in crystallinity of both hdpe and sps. measurements of vicat softening temperature of the hdpe/sps blends show that heat resistance of hdpe is greatly improved upon incorporation of 20 wt% sps.
