N. Clarke et Tcb. Mcleish, SHEAR FLOW EFFECTS ON PHASE-SEPARATION OF ENTANGLED POLYMER BLENDS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 57(4), 1998, pp. 3731-3734
We introduce an entanglement model mixing rule for stress relaxation i
n a polymer blend to a modified Cahn-Hilliard equation of motion for c
oncentration fluctuations in the presence of shear flow. Such an appro
ach predicts both shear-induced mixing and demixing, depending on the
relative relaxation times and plateau moduli of the two components.
