摘　　要：本文用ＴＥＭ和ＴＢＡ研究了不同的成膜溶剂：甲苯、四氯化碳和环己烷对ＳＢＳ形态结构的影响．认为ＳＢＳ的基本形态结构是两相分离的，聚丁二烯相的连续程度按甲苯＜四氯化碳＜环己烷的顺序增强，并证实了界面层的存在，在此基础上提出了ＳＢＳ的结构模型．In this paper, the effect of casting solvents on the morphology of styrene-butadiene-styrene (SBS) block copolymer was studied hi TEM and TBA. These soluents were toluene, carbon tetrachloride and cylohexane. The basic morphology of SBS was two separateol pantses. The continuous degree of PB pbast moresed in the order of toluene, carbon tetrachloride and cyclohexane.The existance of interphase waS proved and a structural model of SBS wes given.
