title: Linking atomistic and mesoscale simulations of water-soluble polymers.
abstract: A link between molecular and mesoscopic simulations for water-soluble polymers is made using the potential of mean force (PMF) method. Mesoscale parameters are adjusted to match selected thermodynamic quantities such as the monomer second virial coefficient or the limiting slope of the monomer adsorption isotherm, which are computed directly from atomistic PMFs. The method is illustrated by computing the bulk and surface interaction parameters (chi parameters in self-consistent field theory) for the adsorption of ethylene oxide (EO) and propylene oxide (PO) polymers from aqueous solution onto silica.
