Coarse-grained Description of Polymer Blends as Interacting Soft-Colloidal Particles
arXiv:cond-mat/0411497 · doi:10.1063/1.1835271
Abstract
We present a theoretical approach which maps polymer blends onto mixtures of soft-colloidal particles. The analytical mesoscale pair distribution functions reproduce well data from united atom molecular dynamics simulations of polyolefin mixtures without fitting parameters. The theory exactly recovers the analytical expressions for density and concentration fluctuation structure factors of soft colloidal mixtures (liquid alloys).
