A viscoelastic constitutive equation is derived for the diffusion flux of an infinitely dilute solute diffusing in a polymeric fluid under steady flow conditions. It is shown that the mass transfer rate of gas into an ideal polymer jet increases with increasing elasticity. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 88: 3256–3263, 2003
