| The thermodynamic consistency of the eXtended Pom-Pom (XPP) model for branched polymers of Verbeeten et al. [J. Rheol., 45(4), 823{843 (2001); J. Rheol., 45(6), 1489{1489 (2001)] is investigated from the perspective of nonequilibrium thermodynamics, namely the General Equation for Non-Equilibrium Reversible- Irreversible Coupling (GENERIC) framework. The thermodynamic admissibility of the XPP model is shown. According to the GENERIC formalism, the parameter α introduced by Verbeeten et al. to predict nonzero second normal stress in shear °ows must ful¯ll the condition 0 <= α <= 1.
