Mixture for stabilizing polyurethanes
 A mixture for stabilizing polyurethanes contains PA1 (a) an amine of the formula I ##STR1## (b) a mixture of the benzotriazoles II and III ##STR2## in which n is chosen so that the mean molecular weight of the mixture is greater than 600, and PA1 (c) .alpha.-tocopherol, if necessary mixed with tris-(nonylphenyl) phosphite, and polyurethanes contain from 0.005 to 5.0% by weight, based on the material to be stabilized, of this mixture.
