Abstract: We present molecular dynamics simulations of a polymer in a solvent of monomers. We have studied the influence of the “quality” of the solvent on the radius of gyration. This is modelled by varying the ϵmp of a Lennard-Jones potential, which describes the interaction of the monomers with the polymer segments. Starting from an isolated chain (ϵmp=0), the introduction of a very small interaction with the solvent causes a large decrease in the radius of gyration. A further increase of ϵmp causes the radius of gyration to increase again.
