The thermodynamics of micelle formation by a polystyrene-b-polyisoprene block copolymer in n-hexadecane, which is a selectively bad solvent for polystyrene, has been investigated. The temperature dependence of the critical micelle concentration (c.m.c.) was determined from measurements of scattering
Abstraet--A calorimetric study was made of micelle formation by a polystyrene-b-polyisoprene block copolymer in n-hexadecane which is a selectively bad solvent for polystyrene. A value of -44.0 + 4.0 kJ mol-~ was obtained for the enthalpy of micellisation, in good agreement with a value of -40.7 +2.
## 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
