Abstract

1,139,575. Polyurethane foams. IMPERIAL CHEMICAL INDUSTRIES Ltd. 14 June, 1966 [28 June, 1965], No. 27275/65. Headings C3C and C3R. Polyurethane foams are prepared by reacting an organic polyisocyanate with a polyol having a molecular weight of at least 300 in the presence of a trialkanolamine, a halogenated hydrocarbon and 0.1 to 5% by weight of the trialkanolamine and halogenated hydrocarbon of a thiobisphenol. The trialkanolamine halogenated hydrocarbon and thiobisphenol are suitably mixed together and then added to the polyisocyanate and polyol or, if desired, they may be mixed with the polyol and the resulting mixture reacted with the polyisocyanate. Suitable polyisocyanates are the tolylene diisooyanatea and 4,41-diphenylmethane diisocyanate. The exemplified polyol is an oxypropylated trimethylolpropane. Examples of trialkanolamines are triethanolamine, triisopropanolamine or the reaction products of propylene oxide with mono- and diethanolamine. The halogenated hydrocarbon preferably has a b.p. not exceeding 75‹ C., e.g. methylene chloride, vinylidene chloride and particularly compounds containing at least one fluorine atom per molecule. Preferred thiobisphenols are 2,21-thiobis-(6-methylphenol), 2,2<SP>1</SP>- thiobis - (4 - methyl - 6 - tert.- butylphenol) and 4,4<SP>1</SP>-thiobis-(3-methyl-6-tert.- butylphenol). The foam forming reaction mixture may also contain e.g. water, catalysts, surface-active agents and flame retardants.
