ROLE OF ADSORPTIONAL LAYERS OF SURFACTANTS IN FORMATION OF POLYEPOXIDES

Thermodynamics of adsorptional layers of siloxane surfactants in simple binary systems simulating the real epoxide compositions has been studied. Microstructure, swelling capacity and adhesional strength of polyepoxides cured in the presence of surfactants in different concentration are characterized. All these parameters of polymers depend essentially on the amount of introduced surfactant, but the dependences are nonmonotonous. The regularities observed are explained by the different structure of adsorptional layers of surfactants formed in reaction systems on the stage of polymers formation.
