  • Publication number: 20140120353
    Abstract: Curable aqueous polyurethane polymer dispersions are described. The dispersion comprises a polyurethane copolymer having pendant (meth)acrylate groups and pendant carboxylic groups along the main chain and a tertiary aminofunctional unsaturated monomer that has reacted in an acid/base reaction with the carboxylic acid groups on the main chain. The dispersion can be applied to the surface of a substrate and cured using ultra-violet or electron-beam radiation to form a cured polyurethane having desired properties that does not emit volatile amine compounds.

  • Publication number: 20130101540
    Abstract: The present disclosure is directed to aqueous dispersions comprising polyurethane and nanoparticles, and processes for preparing the aqueous dispersions. The dispersions comprise aqueous polyurethane dispersions having nanoparticles covalently incorporated into the polymer matrix. The dispersions are prepared by reacting isocyanate groups present on the polyurethane chain ends with free amine groups on a hydroxy- or amino-functionalized nanoparticle to covalently attach the polyurethane and the nanoparticle through urethane or urea linkages, respectively.
