18 p, 477.9 KB Thermodynamics and dynamics of flowing polymer solutions and blends / Jou i Mirabent, David, 1953- (Universitat Autònoma de Barcelona. Departament de Física) ; Casas Vázquez, José (Universitat Autònoma de Barcelona. Departament de Física) ; Criado-Sancho, Manuel (Universidad Nacional de Educación a Distancia (Espanya). Departamento de Ciencias y Técnicas Físicoquímicas)
We review the basic ideas and main results of our analysis of shear-induced effects in polymer solutions and blends. The analysis combines thermodynamic and hydrodynamic descriptions. The flow contribution to the free energy of the solution is described in the framework of extended irreversible thermodynamics, which relates the viscoelastic constitutive equations to a non-equilibrium entropy that depends on the viscous pressure tensor.

6 p, 76.5 KB Shear-induced shift of spinodal line in entangled polymer blends / Criado-Sancho, Manuel (Universidad Nacional de Educación a Distancia (Espanya). Departamento de Ciencias y Técnicas Físicoquímicas) ; Jou i Mirabent, David, 1953- (Universitat Autònoma de Barcelona. Departament de Física) ; Casas Vázquez, José (Universitat Autònoma de Barcelona. Departament de Física) ; Castillo, L. F. del (Universidad Nacional Autónoma de México. Instituto de Investigaciones en Materiales)
We study the shear-flow effects on phase separation of entangled polymer blends by incorporating into the chemical potential a nonequilibrium contribution due to the flow. The results are compared with those of a previous analysis by other authors which did not modify the chemical potential but used a different assumption for the stress tensor of the blend.

3 p, 38.5 KB Legendre transform in the thermodynamics of flowing polymer solutions / Casas Vázquez, José (Universitat Autònoma de Barcelona. Departament de Física) ; Castillo, L. F. del (Universidad Nacional Autónoma de México. Instituto de Investigaciones en Materiales) ; Jou i Mirabent, David, 1953- (Universitat Autònoma de Barcelona. Departament de Física) ; Criado-Sancho, Manuel (Universidad Nacional de Educación a Distancia (Espanya). Departamento de Ciencias y Técnicas Físicoquímicas)
We propose a Legendre transform linking two different choices of nonequilibrium variables (viscous pressure tensor and configuration tensor) in the thermodynamics of flowing polymer solutions. This may avoid some current confusions in the analysis of thermodynamic effects in polymer solutions under flow.
