Abstract: High resiliency polyurethane foam is made from a polyether polyol having an equivalent weight of at least 1000. At least a portion of the polyether polyol is one or more random copolymer(s) formed by polymerizing a mixture of 70 to 95% by weight propylene oxide and 5 to 30% by weight ethylene oxide onto an initiator compound. The random copolymer(s) has a nominal hydroxyl functionality of at least 5, a hydroxyl equivalent weight of at least 1500 g/equivalent and no more than 0.01 milliequivalents per gram of terminal unsaturation. The randomly polymerized propylene oxide and ethylene oxide constitute at least 80% of the total weight of the random copolymer. At least 70% of the hydroxyl groups of the random copolymer are secondary hydroxyls.
