Values of Q and A in the expression ~ = A exp (Q/RT)have been obtained for dilute solutions of fractions of a Bisphenol A polyearbonate in five solvents. The apparent activation energy of viscous flow Q varies with concentration c and molecular weight M according to where Q0 refers to the solvent a
