中文摘要	the effects of three triblock copolymers of poly [styrene-b-(ethylene-co-butylene)-b-styrene] (sebs) of different molecular weight (mw) on the morphology, tensile strength and thermal behavior of isotactic polypropylene/syndiotactic polystyrene (ipp/sps, 80/20) blend are investigated. morphology observation shows that both the medium mw and the lower mw sebs are more effective than the higher mw sebs in compatibilizing the blends. tensile tests revels both the medium and low mw compatibilizer lead to a significant improvement in tensile strength, while the higher mw compatibilizer is efficient in increasing the elongation at break of the blends. the localization of compatibilizers in the blends is observed by mean of sem and the correlation between the distribution of the compatibilizers and mechanical properties of the blends is evaluated. the mechanical properties of the ipp/sps blends depend on not only the interfacial activity of the compatibilizers but also the distribution of the compatibilizer in the blend. addition of the compatibilizers to the blend causes a remarkable decrease in the magnitude of the crystallization peak of sps at its usual t-c. vicat softening points demonstrate that the heat resistance of ipp/sps blend is much higher than that of the pure ipp.
