PURPOSE: A bonded product of a high bonding strength, prepared by adding a specified unsaturated organic compound and an organic peroxide to an olefin polymer, molding the mixture, coating the surface of the molding with an isocyanato group-containing adhesive and bonding the molding to an adhered.
CONSTITUTION: To 100pts.wt. olefin are added 0.1W50pts.wt. organic compound having at least one unsaturated bond and a hydroxyl group in the molecule (e.g., 2-hydroxyethyl acrylate, 2-hydroxypropyl methacrylate), and 0.01W20pts.wt. organic peroxide (e.g., benzoyl peroxide, dicumyl peroxide), and the resulting mixture is molded. The surface of the molding is coated with an isocyanato group-containing adhesive (e.g., solvent type urethane adhesive, water-based vinylurethane adhesive), and the molding is bonded to an adherend.
