The Nature of Self-Adhesion (Tack) of Polymers. I

Abstract

Abstract At the present time, ideas concerning cohesion, adhesion, and self-adhesion (self-sticking) are widely used for explaining the phenomena observed in gluing with polymeric substances. But the investigators, in developing the theory of gluing, pay most attention to cohesion and adhesion. Self-sticking (self-adhesion) has thus far remained unstudied and has no satisfactory explanation. Researches devoted to self-sticking are very few. Mention should be made here of the work of Zhukov and Talmud, who separated self-sticking from the total complex of adhesive properties, proposed the term autohesion, and were the first to study this property experimentally. Furthermore, we must mention the researches of Priklonskaya and of Maslovskii˘ and Popova, who investigated the self-sticking of industrial materials (rubber mixtures). Finally, the question of self-sticking of polymeric substances was touched upon in a very small number of researches of foreign authors. It should be noted however that these researches appeared considerably later than those of the Soviet investigators and are very speculative in nature.
