POLYMER ADHESIVES.

This paper reviews recently published papers reporting progress in development and applications of polymer-based adhesives. Perhaps the most striking aspect of adhesive research in the past year has been on the development of heteropolymers in response to the increasingly stringent demands on performance as adhesives expand their role. One could observe the evolution of new heterophase block and graft polymers of improved performance to supplement the already established diene-arene block polymers which have found their niche in hot melt applications. The survey is presented under headings - structural adhesives; solventless adhesives (hot melt, film, solids reactive liquids, isocyanate, silicone adhesives and sealants, aqueous adhesives); pressure-sensitive adhesives; elastomer adhesives; theory of adhesion; and surface preparation.
