  • Process for preparing graft polymer dispersions and polyurethanes prepared therefrom
    Patent number: 4359571
    Abstract: The present invention relates to a process for the preparation of stable graft polymer dispersions having improved dispersibility by a free radical polymerization of an ethylenically unsaturated monomer under conditions of no-reflux or alternatively under conditions that do not return the evaporated monomer to the dispersion. Polyurethane foams may be prepared from these polymer dispersions.
