Abstract
An aqueous dispersion of polyurethane composites is made by forming a dispersion of urethane prepolymer or polymer and ketone functional molecule by dispersing them in an aqueous media and adding a hydrazine functional molecule. When the ketone functional molecule is derived from levulinic acid and epoxidized vegetable oil, the resulting urethane dispersion has enhanced coalescence with less need for coalescing aids.
