摘要： A stable copolymer dispersion is prepared by addition copolymerization of (1) a monomeric adduct of an active hydrogen compound, e.g., a polyether polyol, and an acrylyl compound such as methacryloyl chloride with (2) ethylenically unsaturated monomer(s), e.g., styrene or a mixture thereof with acrylonitrile, while (1) and (2) are dispersed or dissolved in an excess of an active hydrogen polyfunctional compound such as a polyether polyol. The molar ratio of acrylyl moiety to active hydrogen compound is less than 0.1:1. The resulting dispersion has a controlled particle size and a viscosity such that it is suitably employed in the production of polyurethane foams.

摘要： A low viscosity copolymer polyahl dispersion is prepared by polymerizing polymer particles in a polyahl medium, to a first solids concentration and thereafter diluting the dispersion to a second lower solids concentration. The resulting diluted dispersion has a lower viscosity than if the dispersion were prepared directly at the lower solids level. The invention has particular advantage when used with "all acrylonitrile" dispersions. The copolymer polyahl dispersions are useful in the manufacture of urethane and isocyanurate foams.
