Effects of the solvent on the conformation of a polymeric chain molecule are examined by using a set of polymer-solvent integral equations for correlation functions for the polymer and the solvent. Solutions of the integral equations are used for computing the polymer-solvent distribution, chain conformations, and scaling properties associated with polymer swell and collapse in good and poor solvents. The variation of chain properties with the solvent density and the solvent quality is examined for chains having up to 100 bonds.
