Abstract
The authors present a theory on the dynamics of polymeric melts and concentrated solutions in which the effective medium surrounding the macromolecule is conceived of as an anisotropic nonlinear viscoelastic fluid. The chains surrounding the macromolecule are treated as a set of Brownian particles strongly connected with each other by elastic forces. The Brownian particles are modeled using the Gaussian subchain concept. A stochastic average taken over the immediate neighborhood of a given macromolecule defines a continuum with inherent memory effects which change under deformation depending on the orientation of the macromolecules surrounding the particular chain.
