  White 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. improved processes for the preparation of these polymer dispersions employ either maleate or 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 invention relates to polyols prepared by reacting ethylene oxide with an initiator followed by additional alkylene oxide. The ethylene oxide blocks at the initiator ranges from 1 to 30 weight percent based on the weight of the polyol. Polyurethane foams prepared from these polyols exhibit good air flow and improved load bearing properties.

  公开（公告）日：1988-08-10

  Organic polyisocyanates characterized by allopho­nate linkages are prepared by reacting an organic polyisocy­anate with a mono- or polyhydric compound in the presence of an organo metal catalyst. The catalyst is then deactivated using a compound such as an inorganic acid, organic acid, organic chloroformate or an organic acid chloride. The isocyanates are useful in preparing polyurethane foams.
