Estimation of the Compatibility of Poly(2, 6-Dimethyl-1, 4-Phenylene Oxide) and Poly(Fluorostyrene-co-Bromostyrene)from Dilute Solution Viscosity Measurements

The viscosity behaviour of dilute benzene solutions of poly(fluorostyrene-co-romostyrene)(A) and poly(2, 6-dimethyl-1, 4-phenylene oxide)(B) and of their mixtures has been studied at 25. The viscosity interaction coefficients, kAB, have been calculated from the Huggins slope coefficients of polymer mixtures. The results of the estimation of the compatibility of polymer pairs, according to Krigbaum and Wall, have been compared to DSC findings.
