ABSTRACT:
Polyether polyols may be synergistically stabilized against oxidation by incorporating therewith 4,4'-bis(alphadimethylbenzyl) diphenyl amine and a 2,6-di-t-butyl-4-(lower alkyl) phenol such as 2,6-di-t-butyl-4-methyl phenol or 2,6-di-t-butyl-4-butyl phenol. The stabilized polyols inhibit color formation when employed in the preparation of polyurethane foams.
