Abstract
It is assumed that the interaction parameter used in the Flory-Huggins theory may depend on the mechanical field. The effect of deformation on phase transitions in polymer solutions is considered under this assumption. An expression relating the thermodynamic parameter of interaction between the components to deformation conditions is proposed. Quantitative relations describing shifts in liquidus lines and spinodals of polymer-solvent systems in mechanical fields are derived.
