ABSTRACT:
A polyol composition useful for the preparation of high resilience polyurethane foams comprising (1) from 80 to 99.8 weight percent of a high functionality polyol or a polyol blend having an average nominal functionality between 3.2 and 6, and from 0.2 to 20 weight percent, a subsidiary polyalkylene oxide having a poly(oxyethylene) content greater than 30 percent, or (2) from 50 to 98 weight percent of a high functionality polyol or a polyol blend having an average nominal functionality between 3.2 and 6, from 0 to 0.9 weight percent of a subsidiary polyalkylene oxide having poly(oxyetheylene) content greater than 30 percent, and from 2 to 50 weight percent of a polymer. The average nominal functionality of the polyol composition is between 3.2 and 6. This polyol composition provides greater latitude for varying formulation components in the preparation of high resilience polyurethane foam as with broad density and load ranges.
