Spherulites are growth patterns of average spherical form which may occur in the polycrystallization binary mixtures due to misoriented angles at low grain boundaries. The dynamic spherulites can be described by a phase field model where underlying free energy depends on two variables, namely local degree crystallinity and orientation angle. For solution we suggest splitting scheme based an imp...

The thermal properties and crystallization kinetics of Curdlan propionate, a type bio-based plastic ?-1,3-glucan derivative, were investigated. Melt-spun fibers also prepared, the fiber formation mechanism internal structure analyzed. decrease curve in molecular weight suggests that degradation propionate likely proceeds by random scission. Polarized light microscopy isothermal process showed f...

This study investigates the solid-state structure of a copolymer composed polyethylene glycol (PEG) and azacalixarene, which has two s-triazine rings phenyl alternately crosslinked by amino groups. Azacalixarene derivatives containing low-molecular-weight linker moiety exhibiting an amorphous have been synthesized in previous studies; however, this study, they are crystallized substitution with...
