## Abstract We present a morphological study of the micellization of an asymmetric semicrystalline block copolymer, poly(butadiene)β__block__βpoly(ethylene oxide), in the selective solvent __n__βheptane. The molecular weights of the poly(butadiene) (PB) and poly(ethylene oxide) (PEO) blocks are 26
## Abstract The effect of addition of A homopolymer chains to HEX phases formed by cylindrical micelles obtained by dissolving an AB diblock copolymers in an A selective solvent was investigated. The following general trends were observed: (i) orderβorder transitions from HEXβββGyroid (G)βββLamella
