ABSTRACT:
Graft polymer dispersions in polyoxyalkylene polyether polyols are employed together with flame retardant compounds to prepare flame retardant polyurethane foams. The polymer dispersions employ less than 0.1 mole of induced unsaturation per mole of polyol mixture. Processes for the preparation of these polymer dispersions employ fumarate derived polyetherester polyols or polyetherester polyols prepared by reacting a polyoxyalkylene polyether polyol with a compound selected from the group consisting of maleic acid, maleic anhydride and fumaric acid and an alkylene oxide in the presence of salts and oxides of divalent metals. The polymer dispersions are prepared in the presence of a reaction moderator and employ 50 weight percent or more of acrylonitrile.
