Abstract
From the Rouse—Zimm theory for the viscoelastic properties of dilute polymer solutions, stress relaxation curves were computed for vanishing and for dominant hydrodynamic interaction. The results were converted numerically to creep data by the method of Hopkins and Hamming. Since the steady-state compliances and steady-flow viscosities can be calculated separately, computation of the creep curves afforded a check on the accuracy obtainable with the Hopkins—Hamming method. The primary interest of this work lies in its relevance to the stress relaxation and creep behavior of undiluted bulk polymers.
