Abstract

The structure of sulfonated polystyrene ionomers in chloroform was studied by molecular hydrodynamics and neutron scattering methods. The ionomer containing 1.35 mol % of ionogenic SO3Na groups undergoes the coil-globule transition and transforms to a micellar structure due to attraction of polar groups concentrated in the core surrounded by nonpolar chain fragments. At a sulfonation degree of 2.6 mol %, selfassembly of SO3Na groups with adjacent chain segments to the structure such as a spherical layer, i.e., vesicle (hollow micelle with solvent) with boundaries formed by nonpolar chain fragments, is observed. Vesicular structures in solution associate in pairs. Intra- and interchain associations are significantly enhanced by hydrogen bonds in ionomers with acid groups SO3H (2.6 and 4.47 mol %) which stabilize micellar structures, promoting their assembly into chain clusters and fragments of the simple cubic lattice.
