Abstract
A composition for the adhesive activation of polymeric material. The composition is comprised of a non-resinous quaternary ammonium salt of a polyepoxide wherein the nitrogen atom of the ammonium group is bonded directly to a carbon atom of the polyepoxide and wherein the composition is substantially free of free amine. The composition may be used as a spin finish or topcoat composition and is particularly useful in the preparation of polyethylene terephthalate tire cord which is ultimately incorporated into rubber.
