Adhesion of textile cords to rubber using a butadiene-styrene vinylpyridine rubber latex and an aldehyde condensate-glyoxal reaction products mixture

Claim 1

A composition which consists essentially of (I) a styrene-butadiene-vinylpyridine terpolymer latex and (II) a mixture of from about 10 to 90 percent, by weight, based on the total weight of said mixture, of (A) an aldehyde condensate comprising (1) those represented by formula: ##STR5## wherein each X represents hydrogen, hydroxymethyl, or alkoxymethyl (C 1 -C 4 alkoxy), or (2) those represented by formula: ##STR6## wherein each Y is selected from hydrogen, hydroxymethyl, or alkoxymethyl (C 1 -C 4 alkoxy), and from about 90 to 10 percent, by weight of (B) a glyoxal reaction product comprising: (a) those which are the products of reaction of from about 0.1 to 10 molar proportions of urea with one molar proportion of glyoxal or (b) those which are the products of reaction of 0.1 to 10 molar proportions of urea and from 0.01 to 2 molar proportions of formaldehyde with one molar proportion of glyoxal; provided that each of said (A) and (B) in said mixture contains at least two reaction hydroxyl, hydroxymethyl, or alkoxymethyl groups per molecule.
