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 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) order–order transitions from HEX → Gyroid (G) → Lamella
The dynamic structure of micelles formed by a polystyrene-b-poly(ethylene/propylene) block copolymer in paraffinic solvents has been studied by electron microscopy, photon correlation spectroscopy and LH and 13C-nuclear magnetic resonance. In n-octane below 50 °, the polystyrene core has two compone
