ABSTRACT:
.alpha.- and/or .beta.-tocopherol (vitamin E), optionally in combination with octylated diphenylamines, is combined with a polyether polyol having a molecular weight of from about 300 to about 10,000 to stabilize that polyether polyol. Polyether polyols which are stabilized in this manner are particularly useful in the production of polyurethanes and polyurethane foams with a reduced tendency toward discoloration.
