It is also called flory hawkins interaction parameter, flori action parameter, X12 parameter or interaction parameters. Dimensionless value representing the change of interaction energy between solvent and macromolecule or when macromolecule is polymer blending. The interaction parameters of macromolecule solvent can be calculated by measuring the vapor pressure of macromolecule solution and solvent.
