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
## Abstract Viscosity measurements were made for dilute solutions of three grades of cellulose acetate (acetyl content 39.8%, molecular weight M̄~__v__~ 30270 to 46250) in acetone in the temperature __t__ range of 10° to 35°C. The data satisfied the Mark‐Houwink equation, [η] = __K__M̄, where [η] =
