The Rouse-Bueche-Zimm Theory of polymer viscoelasticity previously was extended to apply to monodisperse polymers with chain entanglements as well as their binary blends. Entangled systems were modeled by assigning enhanced friction and elastic coupling to these entangled points in the 3-dimensional transient networks. The computed linear viscoelastic properties were found to be in excellent agreement with literature data for these systems. A natural extension of these calculations is to predict viscoelastic properties of multicomponent blends from the knowledge of their compositions. The transient network model is not only successful in predicting the linear viscoelastic behavior of monodisperse polymers and binary blends, but also ternary blends. The model takes into account the multitudinous interactions of all chains in the polymer in a very simple manner. 12 references.
