CA 2181606

Polyoxyalkylene polyether polyols suitable for preparation of flexible polyurethane foams are prepared by oxyalkylating an aqueous solution of one or more polyhydric, hydroxyl-functional solid initiators under conditions where both water as well as initiator are oxyalkylated. The polyols have calculated functionali- ties of between about 2.2 and 4.0 and hydroxyl numbers in the range of 10 to 180. The polyols may be used to prepare soft, high resiliency polyurethane flexible foams at low isocyanate indexes.
