采用小角Ｘ射线散射（ＳＡＸＳ）法和偏光显微镜法测定不同组分比的聚四甲基苯撑硅氧烷（ＴＭＰＳ）与１，２聚丁二烯（ＰＢ）共混物的长周期、晶片厚度、无定形厚度及一维结晶度等超分子结构参数及球晶生长形态。结果表明，ＴＭＰＳ／ＰＢ共混物组分比和热历史，将影响系统中非晶共混物不同程度的微相分离及相倒转；相倒转又影响了系统中结晶相ＴＭＰＳ晶体的生成条件，使共混物的上述超分子结构参数产生了不连续的变化。偏光显微镜照片表明，ＴＭＰＳ／ＰＢ共混物是非晶态分散在球晶中，这与Ｒ·Ｓ·Ｓｔｅｉｎ提出的非晶态分散在球晶中的模型相似。
The long period of poly (tetramethylphenylene siloxane) (TMPS) and 1,2-polybutadiene (PB) blends with different composition ratio were determined by small angle X-ray scattering (SAXS) and polarized light microscopy Thickness, amorphous thickness and one-dimensional crystallinity and other supramolecular structure parameters and spherulite growth morphology. The results show that the composition ratio and thermal history of TMPS / PB blend will affect the different degrees of micro-phase separation and phase inversion of amorphous blends in the system. Phase inversion also affects the formation conditions of TMPS crystal in the system, The above supramolecular structure parameters of the blend produced discontinuous changes. Polarizing microscope photographs show that the TMPS / PB blend is amorphous dispersed in the spherulites, similar to the SRS Stein model of amorphous spherulites.
