Abstract

The viscosity behaviour of dilute solution of Polystyrene-Poly(vinylidene fluoride) in dimethylformamide (DMF) in presence of urea has been studied at 25°C. The results show that the polymer mixtures are incompatible in DMF solution in the absence of urea. The influence of urea addition on the degree of compatibility of the polymer mixture has been studied in terms of the compatibility parameters (,,, and ) respectively.
