Abstract
The intermolecular structure of semidilute polymer solutions is studied theoretically. The low-density limit of a generalized Ornstein Zernicke integral equation approach to polymeric liquids is considered. Scaling laws for the dilute-to-semidilute crossover of the random-phase approximation (RPA)-like structure are derived for the intermolecular structure factor on large distances when intermolecular excluded volume is incorporated at the microscopic level. This leads to a nonlinear equation for the excluded volume interaction parameter. For macromolecular size-mass scaling exponents n above a spatial-dimension dependent value, vc= 2/d, meanfield-like density scaling is recovered, but for v
