Latest Patents

Andrea holds a patent for "Crosslinked Polyurethane Dispersions." This patent describes stable aqueous dispersions of crosslinked polyurethane particles that coalesce upon drying to form continuous films. The process involves reacting a mixture of polyfunctional hydrogen compounds, including one with an ionically neutralizable solubilizing group and another with a functionality of three or more, with a diisocyanate to create a non-crosslinked prepolymer. The solubilizing group is then neutralized, and the prepolymer is dispersed in water. Finally, the prepolymer is chain-extended with water or an aqueous solution of a water-soluble diamine to produce an isocyanate-free dispersion of crosslinked polyurethane polymer. Andrea has 1 patent to her name.
