A previously derived general equation, correlating the intrinsic viscosity of a polymer with -~'n, ~w and 2~,, is tested with experimental data. Its application for the calculation of average molecular weights is discussed. Good results have been obtained for the calculation of 2f/" z using experime

Al~tract--An empirical equation relating the intrinsic viscosity of a polymer and its number-, weight-and z-average molecular weights has been used to evaluate the K and a constants of the Mark-Houwink-Sakurada relationship, in cases where data either from monodisperse samples or from samples with k
The rheological response of dilute solutions of high molecular weight polyacrylamides a t low shear rates has been measured using a capillary viscometer that provided for a fivefold variation in shear rate at each concentration. The non-Newtonian effects were found to be significant for polyacrylami
