[Also in Division C4] A stabilized composition, suitable for use in preparing polyurethane foams comprises an organic halogen compound and a polyol, and, as stabilizer, from 0À01 to 10% by weight, based on the weight of the organic halogen compound of 2-(α-methylcyclohexyl)-4,6-dimethylphenol, bis - (2 - hydroxy - 3 - (α - methylcyclohexyl) - 5 - methylphenyl) - methane, triphenyl phosphite, tetraethyl thiuran disulphide, 2 - mercaptobenzimidazole, 7 - amino - 2 - mercaptobenzimidazole, 5,6 - dichloro - 2 - mercaptobenzimidazole or bis - (2 - mercaptobenzimidazol-5-yl)-sulphone. The organic halogen compound may be one of those compounds frequently used as blowing agents or flameproofing agents in polyurethane foam formulations. Suitably the polyol has a M.W. of at least 250 and is the reaction product of one or more alkylene oxides with a compound containing a plurality of active hydrogen atoms. The stability of the compositions is further demonstrated when a basic-reacting material is present e.g. a tertiary amine or a polyol containing primary, secondary or tertiary amino groups.
