Microphase structure and its formation process in combination of macrophase separation, microphase separation and crystallization were investigated for polymer blends containing crystalline-amorphous block copolymers using mainly time-resolved synchrotron small-angle X-ray scattering technique and diffferantial scanning calorimetry. For the systems with a rubbery amorphous component, whether or not crystallization destroyed microphase separation structure in melt depended on its morphology, molecular weight and temperature ; crystallization occurred within cylindrical structure. On the other hand, melt structure was maintained completely for the systems with a glassy amorphous component. The structure formation was not affected by occurrence of microphase separation ; two kinds of miaophase separation structure could coexist even after crystallization. The present study revealed that the crystalline phase could be ananged regularly in the nano-order scale using melt microphase structure as a template.

研究了含有晶体的X射线X射线散射技术和差异扫描平均测量的聚合物混合物，研究了含有结晶的X射线散射技术和扩散扫描平均晶和差异。对于具有橡胶无定形成分的系统，无论结晶是否破坏了熔体的微相分离结构，取决于其形态，分子量和温度。结晶发生在圆柱结构内。另一方面，对于具有玻璃状无定形成分的系统，完全维护了熔体结构。结构的形成不受微相分离的发生影响。即使在结晶后，两种Miophase分离结构也可以共存。本研究表明，使用熔体微相结构作为模板，可以在纳米级尺度上定期遇到晶相。
