A polydisperse case of an entangled linear polymer melts constitutive equation wasstudied. This constitutive equation, proposed by S. Dhole et al. [J. Non-Newtonian FluidMech. 161 (2009) 10–18], based on the reptation theory and the tube model, was tested on apolystyrene in shear (capillary rheometry) and planar extension in a complex flow(fieldwise measurements in a contraction flow) for different level of strain rates. A goodquantitative prediction of all the set of experiments was obtained, using no adjustablenonlinear parameters.
