Abstract

The equilibrium segregation of deuterated polystyrene/poly(2-vinyl-pyridine) diblock copolymers to interfaces between high molecular weight polystyrene and poly(2-vinylpyridine) homopolymers was measured by forward recoil spectrometry. The dependence of the integrated segregation on the equilibrium copolymer concentration in the PS phase is compared to predictions from a mean-field theory in which the copolymer chemical potential is the relevant parameter. Values of the copolymer chemical potential at the micelle transition are obtained from a careful analysis of the data, and are in reasonable agreement with predictions from a simplified theory of micelle formation.
