## Abstract Poly(vinyl phenol)‐__block__‐polystyrene (PVPh‐__b__‐PS) diblock copolymers are synthesized by sequential anionic polymerization with __sec__‐butyl lithium as the initiator. The PVPh‐__b__‐PS diblock copolymer is cast (on a substrate) from several solvent mixtures that contain tetrahydr
## Abstract We present a morphological study of the micellization of an asymmetric semicrystalline block copolymer, poly(butadiene)‐__block__‐poly(ethylene oxide), in the selective solvent __n__‐heptane. The molecular weights of the poly(butadiene) (PB) and poly(ethylene oxide) (PEO) blocks are 26
