Abstract
Computer simulation of dilute solutions of polymer chains has been carried out in the concentration range lower than the critical concentration of coil overlapping. For solvents of various thermodynamic strengths the intermolecular interaction of polymer coils was investigated. The concentration dependence of osmotic pressure π=π(c) was calculated. It was shown that near the θ-point the π(c) curves can be non-monotonic even at very low concentrations as a result of multiparticle interactions. The results obtained make it possible to interpret some anomalies observed in the experimental study of light scattering and osmotic pressure of extremely dilute polymer solutions.
