ABSTRACT:
A polyurethane composition comprising an effective amount of a stabilizer compound represented by the general formula ##STR1## wherein, X is a residue represented the formula ##STR2## and at least three of Y.sub.1, Y.sub.2, Y.sub.3, and Y.sub.4 are residues represented by the general formula ##STR3## wherein R.sub.1 and R.sub.2 are each an alkyl or aralkyl group with the proviso that at least one of R.sub.1 and R.sub.2 is attached through its primary carbon to the nitrogen atom and the total number of carbon atoms of R.sub.1 and R.sub.2 is at least 4, the other one of Y.sub.1, Y.sub.2, Y.sub.3, and Y.sub.4, if present, is a glycidyl derivative residue, and Z is a residue represented by the general formula ##STR4## wherein R.sub.3 and R.sub.4 are the same or different and represent each an alkyl group of 1 to 4 carbon atoms, thereby at least three residues Z represented by the general formula (V) are contained in the compound represented by the general formula (I), and a stabilizer for polyurethane compositions represented by said general formula (I).
