Polyol compositions and their use in the preparation of high resilience polyurethane foams

A composition for use with high index isocyanate and low water content in the preparation of high resilience polyurethane foams comprising:

• (1) a high functionality polyol or polyol blend not being ethylene diamine initiated and being polyoxyalkylene oxide or a blend thereof having an ethylene oxide content of between 8 and 25 percent and having an equivalent weight between 1000 and 4000 and an average nominal functionality between 3.2 and 6, present in an amount of from 50 to 98 weight percent based on the total weight of the polyol composition
• (2) a subsidiary polyalkylene oxide having a maximum functionality of 8 and containing at least one hydroxyl group which subsidiary polyalkylene oxide has an equivalent weight between 300 and 6000 and a poly(oxyethylene) content greater than 30 percent by weight of alkylene oxide, present in an amount of from 0.2 to 0.6 weight present based on the total weight of the polyol composition, and
• (3) a stably dispersed polymer within the high functionality polyol and/or the subsidiary polyalkylene oxide, wherein said polymer is present in an amount of from 2 to 50 weight percent based on the total weight of the polyol composition, or a polymer polyol or a blend of polymer polyols provides from 2 to 50 percent by weight of polymer based on the total weight of the polyol composition;
• wherein the average nominal functionality of the mixture of (1) and (2) is between 3.2 and 6.
