Abstract
The pompon model for branched polymers is re-formulated within a general fr amework of nonequilibrium thermodynamics. While the original model of McLei sh and Larson is found to be thermodynamically admissible, nonequilibrium t hermodynamics strongly suggests several model modifications. As an immediat e consequence, a nonzero second normal-stress coefficient in shear flow is predicted by the modified pompon model.
