ABSTRACT:
An article is provided which comprises a polyolefin first substrate adhered to a second substrate with an epoxy adhesive. The polyolefin first substrate has graft-polymerized thereto at least one monomer selected from the group consisting of sulfonic and carboxylic acids and alkyl esters thereof containing fewer than eight carbon atoms in the ester group, amides and mono- and di-substituted amides, alcohols, amines, and 5-, 6-, and 7-membered heterocyclic rings having at least one oxygen and/or nitrogen atom in the ring, with the proviso that said monomer contain an ethylenically unsaturated polymerizable moiety. The graft-polymerized monomers are in a layer less than 5 micrometers in thickness and contact the epoxy adhesive.
