LOW-VISCOSITY POLYMERIC POLYOLS, A PROCESS FOR THEIR PREPARATION AND THEIR USE FOR THE MANUFACTURE OF POLYURETHANE FOAMS |
摘要 |
A process is described for the preparation of stable, agglomeratefree, low-viscosity graft copolymer dispersions by the free-radical polymerization of olefinic monomers, such as styrene and/or acrylonitrile, with polyol compounds in the presence of a hydroxyl compound modified with castor oil. The use of these graft copolymer dispersions in the manufacture of polyurethane plastics, particularly flexible foams, by the isocyanate polyaddition process is also described.
