Abstract
A variety of pressure-sensitive adhesives were prepared by photocuring mono- and multifunctional acrylate/polyether/benzophenone blends in air. Among the polyethers which have been employed successfully are poly (vinyl ethyl ether), poly(ethylene oxide), poly (ethylene oxide-propylene oxide), and poly(butylene oxide) while representative acrylates include 2-(N-methylcarbamoyloxy) ethyl acrylate, isobornyl acrylate, and neopentyl glycol diacrylate. Peel strengths of approximately 2 pli (adhesive failure) to 9 pli (cohesive failure) were achieved, often in combination with good shear resistance. The photocured products, which are believed to contain acrylates grafted onto low Tg polyethers, contain considerable cross-linked material. A number of important relationships between the properties of these adhesives and both cure and formulating parameters have been uncovered. Use of these relationships can significantly enhance the chances for designing and optimizing superior photocure pressure-sensitive adhesives.
