摘要：

Association between a typical polyelectrolyte, e.g. poly-(acrylic acid), and a divalent metal ion (e.g. Cu(II)) has been studied using different water-methanol mixtures. Preferential solvation coefficients (lambda/c) have been calculated for various solvent compositions. Excellent agreement has been observed between minimum (lambda/c), lowest [eta] and reduced viscosity (eta-sp/c) of the complexes at a specific composition of the solvent. Interpretations have been sought in terms of polyelectrolyte conformational change at this solvent composition.
