An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, trimethylol phenol, and a resorcinol compound, in certain amounts, is useful in forming an adhesive for bonding glass fiber reinforcing elements or cords to rubber compounds or stocks. After dipping the glass fiber cord in the one-step adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing glass fiber cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured to form a composite in which the glass fiber cord is bonded to the rubber by means of said adhesive.

An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, trimethylol phenol, and a resorcinol compound, in certain amounts is useful in forming an adhesive for bonding polyamide or nylon cords to rubber compounds or stocks. After dipping the cord in the adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured. High H-adhesions are obtained with this one-step or single treatment coating dip. It is particularly useful for bonding crystalline polyamides having a large number of aromatic groups in the polymeric structure, e.g., 'Fiber B.'

Method for bonding polyamides to rubber, adhesive for the same, and

Rubber compounds are readily bonded to nylon or polyamides, particularly tire cords of polyamides in which a high proportion of the amide linkages are attached directly to aromatic rings, using a two-step dip process in which the first dip comprises a liquid dispersion or solution of an epoxide having an average of from about two to four epoxide groups per molecule and a molecular weight up to about 600 and the second dip comprises an aqueous dispersion of a mixture of a major amount of a rubbery vinyl pyridine copolymer and a minor amount of a heat reactable 2,6-bis(2,4-dihydroxy phenylmethyl)-4-chlorophenol composition. High H-adhesions are obtained with this process. It is particularly useful for the bonding to rubber compounds of crystalline polyamides having a large number of aromatic groups in the polymeric structure, e.g., 'Fiber B'.
