Abstract
Rubber compounds are readily bonded to reinforcing elements, particularly tire cords of glass fibers, using a one-step dip process in which the dip contains an alkaline aqueous dispersion of a mixture of a major amount by weight of a rubbery vinyl pyridine/styrene/butadiene terpolymer and a lignin sulfonate-resorcinol-formaldehyde reaction product. Good adhesion of the cords to a rubber compound are obtained with this process.
