Abstract
Abstract An adhesive composition which shows improved stickiness and adhesive property at room temperature and exhibits an excellent adhering ability in a short time is prepared by compounding (a) an acrylonitrile-containing copolymer having carbon-to-carbon double bond (b) a phenol-polysulfide resin (c) a metal oxide, and (d) a polyfunctional electrophilic reactive compound containing at least two electrophilic reactive groups.
