THE CRYSTALLIZATION BEHAVIOUR OF BLOCK COPOLYMER/HOMOPOLYMER BLENDS I. INFLUENCE OF NONSPHERICAL MICELLE ON CRYSTALLIZATION BEHAVIOUR IN DILUTE SOLID SOLUTIONS

The effect of micelle on crystallization behaviour of dilute poly(methyl methacrylate-b-tetrahydrofuran) diblock copolymer/tetrahydrofuran homopolymer, dilute poly (ethylene-b-styrene-b-ethylene) triblock copolymer/ethylene homopolymer solutions has been studied. The results show that with the structural teansitions from spherical to nonspherical micelle in the blends, great changes in the nucleation and spherulite morphologies take place.
