We have measured the solubility of mixtures of polybutadiene and polystyrene in toluene, benzene, and carbon tetrachloride, using polymers of various molecular weights and mixed in various proportions. The equations developed by Maron for solutions of nonelectrolytes have been modified for three components and for solutions of low molecular weight polymers at high concentrations. The application of these equations has provided estimates of the polymer–polymer interaction parameters χ 23 . The polymer–solvent interaction parameters χ 12 and χ 13 apparently are functions of the concentration and are not readily obtained from the present limited data.
