    Abstract: Mixtures which are used for the production of polyurethane foam and which contain amines having primary or secondary aliphatic hydroxyl groups, and also customary quantities of trichlorotrifluoroethane and/or trichlorofluoromethane as a blowing agent, can be stabilized against the premature reaction of the components by adding 0.05 to 5% by weight of 2,4-diphenyl-4-methylpentene in which the ratio of the 2,4-diphenyl-4-methyl-1-pentene isomer to the 2,4-diphenyl-4-methyl-2-pentene isomer is 1:1 to 9:1, the percentages relating to the chlorofluoroalkane. In particular, these mixtures can be stabilized by adding 0.1 to 5% by weight of a mixture consisting of 45 to 89% by weight of 2,4-diphenyl-4-methyl-1-pentene, 10 to 45% by weight of 2,4-diphenyl-4-methyl-2-pentene and 1 to 20% by weight of 1,1,3-trimethyl-3-phenylindane.
