In accordance with the memory function of Gaussian chain constraints in entangled polymer melts a set of material functions related to a certain test flow are formulated from the O-W-F type constitutive equation by the appropriate selection of the Cauchy-Green and Finger tensors. The dependences of these material functions on the strain rate and the dependences of the linear viscoelastic functions on the primary molecular weight distribution and the entanglement sites sequence distribution on polymer chain ...
