ABSTRACT:
Mixtures containing active hydrogen compounds such as polyols and aminoalcohols useful for the production of polyurethane foams and also containing trichlorofluoromethane or 1,1,2-trichloro-1,2,2-trifluoroethane as foam blowing agent, are stabilized against reaction of the active hydrogen compound(s) with the chlorofluorohydrocarbon by incorporating a stabilizing amount of amylene, ortho-(isopropenyl) aniline or diisobutylene.
