Abstract

Foamed polyurethanes are formed by reaction in presence of an inert liquid of low B.Pt. of an organic polyisocyanate with an OH-containing polyester having at least 3 isocyanate-reactive groups/molecule, more than 50 molar per cent of the acid residue in the polyester being phthalic or substituted phthalic acid residues, and the polyester being obtained by reacting phthalic anhydride or substituted phthalic anhydride with a polyhydric alcohol having at least 3 OH groups and with an alkylene oxide. Substituted phthalic anhydrides mentioned are tetrabromo- and tetrachloro-phthalic anhydride. Suitable polyhydric alcohols are glycerol, trimethylolmethane, trimethylolpropane, erythritol, pentaerythritol and methyl glycoside. Alkylene oxides mentioned are ethylene, 1,2-propylene, butylene, and epichlorohydrin. Any of the conventional di- or tri-isocyanates may be used. Preferred inert liquids are halogenated hydrocarbons. Water may be included as an additional gas generator. Plasticizers or flame-proofing agents, e.g. tris-b -chloroethyl phosphate may be included in the reaction mixture. If desired the polyester may be mixed with up to an equal weight of a polyether with at least 3 OH groups per molecule. Conventional catalysts, surface-active agents, cross-linking agents, foam-stabilizing agents, colouring matters, fillers, plasticizers and antioxidants may also be incorporated.
