| Research Abstract |
Crystalline/crystalline block copolymers often show the formation of interpenetrating spherulites, where the spherulitic growth of one component continues inside the spherulite of the other component. In this study, the formation of lamellar structure in the crystalline block copolymers and crystallization and diffusion in the interlamellar amorphous regions were investigated. we concluded that (i) the uncrystallized components are confined in the interlamellar regions of the spherulites of the crystallized component, (ii) the crystallization kinetics in the interlamellar regions are largely influenced by both interlamellar spacing and chain connectivity between the blocks, and (iii) molecular diffusion in the amorphous interlamellar regions of the copolymers can be controlled by adjusting the crystallization conditions.
