概要 Miscible blends of three crystalline polymers, namely poly(butylene succinate) (PBS), poly(ethylene succinate) (PES), and poly(oxyethylene) (POE), exhibited interpenetrating spherulites. PBS and PES were immiscible above the melting points, Tm, of these substances, while ternary blends with POE showed miscibility. PBS and PES exhibited the same spherulitic growth process as in a miscible binary blend when they were crystallized from a homogeneous ternary melt. Spherulites of PBS, which is the highest-Tm component, filled the whole volume first. Then, the blends showed either two types of crystallization processes. One was successive nucleation and growth of PES and POE spherulites. The other was simultaneous growth and the formation of interpenetrating spherulites of PES and POE inside the PBS spherulites.
