ABSTRACT:
An aqueous composition comprising an alkaline rubbery vinyl pyridine latex, a water dispersible or soluble epoxide and a polyfunctional amine can be used to treat a polyamide reinforcing element, e.g. a poly(p-phenylene terephthalamide) cord, to increase the adhesion of the cord to rubber. Further improvements in adhesion can be obtained if the cord before treatment with the aqueous composition is exposed to a cold gas plasma of air, N.sub.2, He, Ne or Ar or mixture thereof at up to about 300 watts of power for a few seconds to several minutes to improve its adhesion to rubber.
