ABSTRACT:
The present invention provides waterborne reactive functional latex compositions having pendant reactive functional groups. The reactive functional latex is formed by free-radical emulsion polymerization of monoethylenically unsaturated monomers containing at least one amide functionality with other copolymerizable monoethylenically unsaturated monomers. The amide functionality on the latex polymer is transformed into an isocyanate and/or amine functionality by addition of an alkali hypohalide. The isocyanate and/or amine groups are subsequently react with a multifunctional additive having at least one functional group suitable for reaction with an isocyanate or amine group and attachment of the additive to the polymer particle, and another functional group that remains pendant.
