Abstract
A new and extended formulation of the random phase approximation (RPA) in the study of statics and dynamics of multicomponent polymer mixtur es is presented. The new formulation simplifies the implementation of the RPA in both compressible and incompressible mixtures and allows th e inclusion of hydrodynamic interaction in the dynamics of polymer mel ts in the RPA. The dynamics of copolymer melts with hydrodynamic inter action is studied in detail as an illustration of the extended formula tion, and the variation of the first cumulant as a function of the wav enumber and interaction parameter is obtained.
