Abstract
Abstract Crosslinkable ethylene-vinyl acetate copolymer resins are rendered amenable to forming adherent laminates with crosslinkable silicone rubber by coating the surface of the ethylene-vinyl acetate resin with a solution of a silane or a member of the class of compounds known as polyfunctional monomers prior to adhering the resin to the silicone rubber.
