Two-parameter model predictions and theta-point crossover for linear-polymer solutions / S. Caracciolo, B.M. Mognetti, A. Pelissetto. - In: THE JOURNAL OF CHEMICAL PHYSICS. - ISSN 0021-9606. - 128:6(2008), pp. 065104.065104.1-065104.065104.12.
Abstract:
We consider the first few virial coefficients of the osmotic pressure, the radius of gyration, the hydrodynamic radius, and the end-to-end distance for a monodisperse polymer solution. We determine the corresponding two-parameter model functions which parametrize the crossover between the good-solvent and the ideal-chain behavior. These results allow us to predict the osmotic pressure and the polymer size in the dilute regime in a large temperature region above the theta-point.
