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.

Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
