PREPARATION AND WETTABILITY OF TERMINALLY CHLOROPHENYL-SUBSTITUTED CARBOXYLIC ACID FILMS,
Abstract
Surface-active compounds can be designed to adsorb on solid surfaces to increase the adhesion of liquids, protective coatings, and resins. Often it is feasible to fulfill these requirements without necessitating a chemical reaction with both the adherend and adhesive. Various terminally substituted chlorophenylalkyl mono- and polycarboxylic acids were designed as potential adhesion promoters for certain classes of adherends. Methods were evolved for preparing an adsorbed monolayer of each compound by the melt retraction and other techniques. The wettability properties and the high critical surface tension obtained were consistent with values to be expected for such chlorine-rich surfaces. Moreover, the wettability proved insensitive to changes in homology and structure in these promoter molecules. Similarly, no changes in wettability were observed when the metal adherend was changed. The future implications of these results for improving the adhesion of protective coatings and adhesives were considered. (Author)
