Abstract: Flame-resistant rigid polyurethane foams are prepared by reacting a composition containing esters of phosphorus oxy-acids with polyhydroxy polyoxyalkylene glycol ethers of cyclic sugars, prepared by reacting the sugar or its monohydrate with at least one phosphorus oxy-acid or oxide to form a partial ester of a phosphorus acid and subsequently reacting the partial ester with at least one alkylene oxide selected from ethylene oxide, propylene oxide, epichlorhydrin and butylene oxide (see Division C2) with an organic polyisocyanate, in the presence of a blowing agent, a foam stabilizing agent, and a catalyst system for the foaming reaction.  The initial phosphate ester has an acid value of less than 2, a hydroxyl number of more than 280, and a phosphorus content of between 1 and 10% by weight. Polyaryl polyisocyanates are preferred, and the catalyst may be a tertiary amine and/or a tin salt or an organo-tin compound, and an aliphatic halogenated alcohol may be present in the reaction mixture.ALSO:Compositions containing esters of phosphorus oxy-acids with polyhydroxy polyoxyalkylene glycol ethers of cyclic sugars are prepared by reacting the sugar or its monohydrate with at least one phosphorus oxy-acid or phosphorus oxide to form a partial ester of a phosphorus acid and subsequently reacting the partial ester with at least one alkylene oxide selected from the group consisting of ethylene oxide, 1-2 propylene oxide, epichlorhydrin and butylene oxide, whereby a mixture of hydroxy compounds is formed having an acid value of less than 2, a hydroxyl number of more than 280, and a phosphorus content of between 1 and 10% by weight, both of said reactions being carried out in a polar solvent which is substantially non-reactive with regard to the sugar, the alkylene oxide and the phosphorus oxy-acid or oxide. Specified cyclic sugars are sucrose, glucose, manrose, arabinose, fructose and a -methyl glucoside, and specified oxy-acids and oxides of phosphorus are H3PO4, H4P2O7, H6P4O13 and P2O5.  The phosphoric acid may be used in the ratio of one to three moles for every mole of sugar, and this reaction is preferably carried out between 40 DEG  and 100 DEG  C.  The product is a mixture of partial esters having on average about one phosphate group per sugar molecule. This is then reacted with the alkylene oxide, e.g. at 80 DEG  to 100 DEG  C.  In a modification of the process the sugar is first reacted with the alkylene oxide and the products thereafter reacted with the phosphorus oxy acid or oxide to form the partial ester.  The product preferably has an average of 4 to 8 hydroxy groups per molecule and a viscosity of less than 20,000 centipoise at 25 DEG  C.  Suitable solvents for the preparation of the partial ester are dimethyl dioxane, triethyl phosphate or tri-(chloroethyl) phosphate, but preferably dioxane or dimethyl formamide are used for both stages of the reaction.  The compositions are used in the making of polyurethane foams (see Division C3).
