On the other hand, in the Rouse regime, Eq. (283) yields Dc $ T $ c3=4 Z0 x ð284Þ 46 m. muthukumar since xH $ x $ cÀ3=4 . For semidilute solutions at low salt concentrations, Dc follows from Eqs.

In this limit the equilibrium scattering function gðkÞ exhibits a peak at kà ¼ xÀ1 . Approximating gðkÞ in Eqs.
