IMPROVED FILLED POLYURETHANE DISPERSIONS

摘要

Filled polyurethane dispersions having good tensile strength and elongation properties are comprised of water having therein particulate filler and polyurethane particles, wherein the polyurethane particles are comprised of a polyurethane having therein a elasticity rendering chain extension linkage of a low molecular weight polyoxypropylene diamine. These dispersions are useful for adhesives and carpet backings.
