| 摘 要： | 用ＳＡＸＳ法和偏光显微镜研究了ＰＴＭＰＳ均聚物和ＰＴＭＰＳ ＤＭＳ多嵌段共聚物熔体结晶的亚微观结构．结果表明ＰＴＭＰＳ和ＰＴＭＰＳ ＤＭＳ的亚微观结构参数，和球晶形态、晶体界面自由能表观积及基本物性参数等存在密切相关性．当ＤＭＳ含量为５０％时亚微观结构参数均显示一个转折变化过程，此时，球晶形态、晶体界面自由能、熔点、玻璃化温度和结晶度指数亦呈现一个突变过程．

| Abstract: | The microstructure of PTMPS and PTMPS DMS were studied by SAXS and polarzing microscope.The results showed that the morphology of spherulites,the crystal surface free energies, T m,T g ,crystallinity index(d,s,c) were in close relationship with long spacing,crystal thickness,amorphous thickness and crystallinity index of one dimension.A turning point was present at 50% of DMS content for any curve of above parameters vs.DMS content. |
