Abstract
The diffusion properties of two polymers in saline, namely dextran and albumin, have been followed by measurements of the unidirectional fluxes of their tracer (labelled) counterparts. The relationships between the diffusion coefficients obtained by measurement of the forward and back unidirectional fluxes to the polymer mutual-diffusion and intradiffusion coefficients have been analysed for semi-dilute polymer concentrations.Keywords
