Exploration and validation of random phase approximation (RPA) effects on the observed dynamical scattering from polymer mixtures.
The structure of polymer blends is commonly described in terms of the RPA approximation, that considers incompressibility and interactions in terms of the Chi-parameter. The dynamics of such blends also needs dynamic RPA corrections that for dynamically asymmetric systems could turn out to be very significant. Using a blend of short un-entangled polyethylene in a highly entangled matrix this proposal will demonstrate the huge distortions of the short chain dynamic structure factor by the RPA caused intermixing with the dynamics of the long chain. The proposal serves to validate a code that will allow very generally to correct for dynamic RPA effects with the perspective to become a standard correction program.
