Calculations on the Doi-Edwards Model for Concentrated Polymer Systems

  • P. K. Currie

Abstract

Recently, Doi and Edwards 1,2,3,4have derived a constitutive equation of the BKZ single-integral type from a molecular model for polymer melts, using concepts and techniques derived from the theory of rubber elasticity. The model is valid for all possible flows of the melt, and thus predicts a theoretical correlation between the behaviour of the melt in shear and its behaviour in other flows, such as extension. The correlation between shear and extensional flows is currently of some interest, and therefore the predictions of the Doi-Edwards model have been studied in some detail.
