Oligomers of Poly ( Ethylene Oxide ) : Molecular Dynamics with a Polarizable Force Field

A semi-empirical force-field for simulating oligomers of poly(ethylene oxide) is developed with the united atom representation for methyl and methylene groups. Polarizability of groups is mimicked by polarizable finite dipoles. The force field parameters are adjusted using both empirical data (density, dipole moments, dielectric constant) and ab initio… CONTINUE READING
