Popis:	A brief review of the literature concerning damped Debye lattices as models for viscoelastic relaxation in the primary transition region is presented. We have observed that polystyrene plasticized with dioctylsebacate behaves in a fashion which is inconsistent with previous predictions based on this model. We have suggested an expanded interpretation of the model which predicts that plasticizers with solubility parameters appreciably different from that of the polymer will behave differently from diluents with the same solubility parameter as the polymer. The results of further experimentation are in accord with this new prediction. Our work supports the contention that the damped Debye lattice is a viable model and clearly demonstrates that interchain interactions are important in determining physical properties in the primary transition region.
