Kinetic theory and rheology of bead-rod models for macromolecular solutions. II. Linear unsteady flow properties

For pt.I see ibid., vol.60, no.5, 2111 (1974). Equations of motion are derived for an equivalent macroscopic continuum at low velocity gradients. A general method is presented for obtaining the relaxation modulus of any model without internal potentials. Two cases are considered: a rigid model with two, equal, principal moments of inertia; and a freely jointed three-bead-two-rod model. It is shown that dominant relaxation times exist for each model.
