The role of diffusion phenomena in polymer-to-polymer adhesion

In the present paper different views concerning polymer-to-polymer adhesion were considered and the theory suggested whereby adhesion of high polymers as well as autohesion is reduced to diffusion of chain molecules or their segments and to the formation of a sturdy bond between the adhesive and the adherend as a result. From the viewpoint of the suggested theory the influence of such factors as the duration of contact between the adhesive and the adherend, contact temperature, molecular weight of the adhesive, shape and polarity of macromolecules, and phase state of polymers was considered and explained.
