The model is investigated for viscometric flows. It was shown that the model gives a good description of non-linear effects of simple shear polymer flows: viscosity anomalies, first and second normal stresses, non-steady shear stressesenRheologyLinear Polymer Melts and SolutionsConstitutive EquationMesoscopic ApproachArticle
