| Research Abstract |
Binary blends of crystalline polymers often show the formation of interpenetrating spherulites, namely, the spherulitic growth of one component inside a spherulite of the other component. We have shown, by analyzing the formation process and the spherulitic growth rate of interpenetrating spherulites, (1) that the crystallization takes place mainly in the interfibrillar and interlamellar regions of a spherulite in a blend and copolymer systems, respectively, (2) the influence of existing crystals on the crystalline morphology and growth process of the other component, and (3) the effect of interblock bonds of block copolymers on the molecular mobility. The obtained research results indicate a possibility of a novel guideline for designing a material with use of amorphous spaces inside spherulites.
