| abstract | Phosphorus containing ethers and polyethers are prepared by reacting an alkylene oxide e.g. in amount 3-120 moles with tris-hydroxymethyl phosphine oxide and/or tris-hydroxymethyl phosphine sulphide. The alkylene oxide may be an aliphatic 1, 2-alkylene oxide e.g. ethylene, propylene, butylene oxides, epichlorohydrin, epibromohydrin or cyclohexene oxide, tetrahydrofuran, styrene or a subtituted styrene oxide. The condensation is usually carried out at 50-250 DEG C. with an acid or basic catalyst. In an example a tris-hydroxy methyl phosphine oxide/epichlorohydrin condensate is prepared by heating the reactants in an autoclave in the presence of N-ethyl morpholine as catalyst. Specifications 816,069 and 892,136 are referredALSO:Flame-retardant polyurethanes are produced by reacting an organic polyisocyanate with a condensation product (A) of at least one alkylene oxide and tris-hydroxymethyl phosphine oxide (T.H.P.O.) and/or tris-hydroxymethylphosphine sulphide (T.H.P.S.) The alkylene oxide may be an aliphatic 1, 2-alkylene oxide e.g. ethylene, propylene or butylene oxides, epichlorohydrin, epibromohydrin or cyclohexene oxide, tetrahydrofuran, styrene or a substituted styrene oxide. The condensation is usually carried out at 50 DEG -250 DEG C. with an acid or basic catalyst and with 3-120 moles of alkylene oxide per mole of phosphorus compound. An organic nonphosphorus-containing polyhydronyl compound may also be present e.g. a polyether, polyester or polyesteramide containing 2-4 hydroxyl groups and having a molecular weight of at least 400 preferably 1,000-4,000. The condensation product (A) may be present in amount to provide 0.1 to 20% by weight of phosphorus in the polymethane. Water may be present to give a foamed product. Tertiary amines and/or organo-tin compounds and silicone oils may be added as catalysts and cell controlling agents. In the examples a T.H.P.O./epichlorohydrin condensation product was added to (1) a glycerolpropylene oxide condensate and toluene diisocyanate, a silicone, dibutyltin dilaurate, triethylene diamine, N-ethylmorpholine and water (3) a condensate of propylene oxide with a polyhydric alcohol ("Daltolac 41" Registered Trade Mark) (5) a polyester (Daltolac 21) and an octyl phenol/ethylene oxide surfactant. Specifications 816,069 and 892,136 are referred to. |
