• 中文摘要： A quasi-thermodynamic model for expansion of polymer configuration in solution is investigated. The model is based on Gaussion distribution of segments and mean field theory of polymer solution. An in-homogenous contribution to the free energy of solution is proposed. It arises from the nonhomogeneous distribution of polymer segements. This effect considered. Some numerical consequence for the case polydimethylsiloxane+cyclohexane solution is calculated. Our theory predicts a larger value a than the case without inhomogeneous effect being considered. The difference becomes less significant at higher molecular weight.
