Abstract
This invention relates to a latex for utilization in adhesive compositions for bonding synthetic fibers to natural or synthetic rubber. These latices can be produced at reduced cost and their utilization results in improved performance characteristics. This invention more specifically discloses a latex which is particularly useful for adhering synthetic fibers to rubber which is comprised of (a) water, (b) an emulsifier and (c) a polymer which is comprised of repeat units which are derived from (i) a conjugated diolefin monomer, (ii) a vinyl aromatic monomer, (iii) 2-vinylpyridine and (iv) a vinyl aldehyde monomer. The present invention further discloses a process for adhering synthetic textile fibers to sulfur vulcanizable rubbers comprising the steps of (I) immersing said fibers in an aqueous dispersion of (1) resorcinol, (2) formaldehyde and (3) a latex which is comprised of (a) water, (b) an emulsifier and (c) a polymer which is comprised of repeat units which are derived from (i) a conjugated diolefin monomer, (ii) a vinyl aromatic monomer, (iii) 2-vinylpyridine and (iv) a vinyl aldehyde monomer, to produce dipped fibers; (II) drying said dipped fibers to produce dried dipped fibers; (III) placing the dried dipped fibers in contact with the sulfur vulcanizable rubber; and (IV) curing the sulfur vulcanizable rubber while it is in contact with said dried dipped fibers.
