ABSTRACT:
A coupling agent for chemically linking metal substrates to thermoset polymers is composed of a hydrophobic polymer backbone having functional groups attached thereto at spaced intervals, the functional groups having the ability to form chemical bonds to both the metal substrate and the thermosetting polymeric resin. In a preferred embodiment, the hydrophobic polymeric coupling agent comprises mercaptoester functional groups placed along a strong, hydrophobic polymeric backbone. This polymeric backbone preferably comprises polyethylene resulting in an ethylene mercaptoester (EME) copolymer.
