Rubber adhesive compositions containing vinyl pyridine latex polymers with alternate nitrogen monomers

摘要

The invention relates to polymeric latexes that can be used in adhesive compositions, which provide improved bonding of rubber articles to rubber reinforcing articles. The adhesive composition includes a single or a blend of polymeric latexes comprising a conjugated aliphatic monomer, a vinylaromatic monomer, a vinylpyridine monomer, and a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality. Use of the monomer comprising a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality allows for reduced amounts of the vinylpyridine monomer in the latex, and enhances the bonding properties of the adhesive composition. Use of the adhesive composition provides economic and chemical advantages for the preparation of reinforced rubberized articles.
