AMtraet--A method tmethod 2L) has been proposed for evaluation of the unperturbed chain dimension A from the molecular weight dependence of the molecular friction coe~cient, derived from sedimentation and ditl'usion coefficients. This method is widely applicable when the unperturbed chain is non-Gau

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
