- Abstract
- We extended the previous lattice model for polymer solution systems to binary polymer blend systems. Based on Muller's Monte-Carlo simulation data for symmetric system (r(1) = 32 and r(2) = 32), the energy of mixing is correlated as a function of temperature and composition using an empirical expression. In addition, we introduce new universal functions which reflect the characteristics of polymer-polymer miscibility behaviors. In associated blend systems, specific interactions between polymer segments are considered by using a secondary lattice. Using only one or two adjustable parameters, the proposed model satisfactory correlates the experimental data of real polymer blend systems with greater accuracy than those of other models.
