Abstract Recently developed techniques permit the estimation of the surface free energy of polymers and the separation of this free energy into dispersion and hydrogen‐bonding components. These techniques have been used to calculate the thermodynamic reversible work of adhesion of a vinylidene chloride copolymer coating to propylene film. The changes in work of adhesion upon immersion of the coated polypropylene in water and surfactant solutions were calculated. When the calculated work of adhesion was negative, spontaneous separation of the coating from the polypropylene occurred upon immersion in all cases. When the calculated work of adhesion was positive, no separation was observed in agreement with theory.
