Abstract
The rheological equation of state derived in Part I on the basis of relaxation equations of chain dynamics is analyzed for the steady and transient shear and uniaxial elongational flows of monodisperse polymers. The effect of superslow relaxation processes associated with basic macro-molecular motions that occur on a characteristic scale essentially greater than the so-called distance between entanglements was investigated in these flows. It is shown that the relaxation times in the region of linear and non-linear viscoelasticity are self-consistent. Theoretical predictions are in good agreement with the experimental data for melts of nearly monodisperse flexible polymers.
