Zusammenfassung

The polymer reference interaction site model (PRISM) equations for the collective structure of macromolecular liquids are simplified using the Wiener Hopf factorization technique. This approach is expected to be useful in systems exhibiting strongly different length scales. As an application, melts and solutions of Gaussian flexible polymers are considered. It is shown that PRISM theory in agreement with experiments predicts liquid like packing for high polymer concentrations and mean field like scaling laws for the dilute to semidilute crossover at the theta-temperature. In a systematic expansion the range of validity and the leading corrections to the low density scaling law description are calculated.
