## Abstract The existence of micelles of polystyreneโ__block__โpoly(ethylene/propene) in solutions of polystyrene in toluene was investigated. Toluene is a good solvent of both copolymer blocks whereas polystyrene and poly(ethylene/propene) are immiscible polymers. The presence of homopolystyrene a
## Abstract Investigations on the selfโassembly of block copolymers in solution have in some way a less wellโstudied history than the study of their phase separation in the solid state, and many aspects are yet not completely understood. Here we focus on the behavior of a specific class of copolyme
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.
