ABSTRACT HALOFUNCTIONAL MONOMERIC ADHESION PROMOTERS AND ADHESIVE COMPOSITIONS Polymeric materials modified with about 0.1 to 10, preferably 2 to 8, percent by weight of certain halofunctional monomeric materials substantially improve adhesion between an elastomeric substrate and a metal surface by improving bonding performance at the elastomer-adhesive interface and by eliminating the need for relatively large amounts of additional adhesive components such as nitroso or carbamate compounds. A preferred embodiment of the invention involves a copolymer derived from a halobutadiene monomer and .alpha.-halo-substituted monomeric compounds wherein the .alpha.-halo-substituted compound is present in an amount from about 0.1 to 10, preferably 2 to 8, percent by weight of the copolymer. A typical halobutadiene monomer is 2,3-dichlorobutadiene-1,3, while typical .alpha.-halo-substituted compounds include .alpha.-chloroacrylonitrile, .alpha.-bromo- acrylonitrile, ethyl-.alpha.-bromoacrylate, and ethyl-.alpha.-chloroacrylate.
