Abstract
A stable, low viscosity polymer/polyisocyanate dispersion wherein the polymer is produced by polymerizing an ethylenically unsaturated macromolecular monomer, a functional monomer, and another ethylenically unsaturated monomer, together with a polyurethane foam, elastomer, adhesive, sealant, or coating produced therefrom and a method for fabricating the foam.
