31 Oct 1997 | | Subject: | Soft Condensed Matter | cond-mat.soft | | Abstract: | We study the dynamics of the phase behavior of a polymer blend in the presence of shear flow. By adopting a two fluid picture and using a generalization of the concept of material derivative, we construct kinetic equations that describe the phase behavior of polymer blends in the presence of external flow. A phenomenological form for the shear modulus for the blend is proposed. The study indicates that a nonlinear dependence of the shear modulus of the blend on the volume fraction of one of the species is crucial for a shift in the stability line to be induced by shear flow. | | Source: | arXiv, cond-mat/9710348 | | Services: | Forum | Review | PDF | Favorites | |
