ABSTRACT:
Stable graft polymer dispersions are prepared employing in situ free radical polymerization of ethylenically unsaturated monomer or monomers in an amine-terminated polyoxyalkylene polyether polymer. These dispersions are useful in the preparation of polyurethane foams which have improved tensile strength, elongation, load deflection and tear strength properties.
