ABSTRACT:
A stable dispersion of a polymer in a polyol which imparts improved combustion resistance to polyurethane foams prepared therefrom wherein the polymer is a free-radical initiated copolymer containing from about 0.5 to 75 weight percent, based on the copolymer, of acrylonitrile and from about 25 to 99.5 weight percent, based on the copolymer, of at least one other polymerizible ethylenically unsaturated monomer and wherein the copolymer is characterized by a crosslinking coefficient of less than 55.
