Abstract
This paper discusses the effects of screened hydrodynamic interactions in ternary polymer solutions. The inclusion of a screening
length
in the Oseen tensor allows a good description of the wavevector dependence of the relaxation frequencies characterizing the
mixture. In the limit of infinite screening length
, the full hydrodynamic interaction is recovered whereas for infinitely short length
, the Rouse behavior is obtained. The method can be applied to arbitrary mixtures but for simplicity it is presented here
in the symmetrical case.
