Abstract: An adhesive composition is described comprising unpolymerized cyclic olefin, a ring opening metathesis polymerization (ROMP) catalyst or precatalyst thereof, and one or more adhesion promoter polymers. In one embodiment, the adhesion promoter is a polyolefin comprising maleic anhydride or silicon-containing moieties. In one embodiment, a combination of at least one polymeric polyisocyanate and at least one polyolefin comprising maleic anhydride or silicon-containing moieties provides a synergistic improvement. In another embodiment, a polymeric polyisocyanate adhesion promoter comprising oxygen atoms in the backbone has been found useful for bonding substrates such as polyamide, polyether ether ketone, or polyether imide. Also described are methods of bonding a substrate and articles, such as an electric battery cold plate assembly.
