Abstract
An aqueous adhesive composition is provided which comprises a water-soluble condensation polymer obtained by subjecting a specific copolymer having an alkoxyl group and a specific alkoxysilane to hydrolysis-condensation, and an aqueous medium containing the condensation polymer. This composition can firmly bond non-sulfur-curable elastomer materials to various adherends such as metals; this has been hitherto difficult. A high-grade adhesion and superior heat resistance and oil resistance can be attained. No organic solvent is contained, promising an environmental safety.
