摘要：
A segmental interaction model containing the combinatorial, free-volume and energetic contributions to the excess Gibbs energy has been developed. The energetic contribution is based on the solution of segment concept. The model has been applied to the system poly(vinyl alcohol)/water between 330 and 420 K. The closed loop diagram, the lower and upper critical temperatures are correlated, using weakly temperature dependent UNIQUAC parameters.
