we discuss the effect of spherical micelle on the crystallization behaviour in dilute poly (methyl methacrylate-b-tetrahydrofuran) diblock copolymer/tetrahydrofuran ho-mopolymer solutions. The results show that even for very small copolymer volume fractions
micelles may restrict the nucleation of polytetrahydrofuran obviously for which a good explanation can be made according to the micelle theories developed by Leibler
