ABSTRACT:
Novel polyether polyols made by alkoxylating a mixture of initiators are described. The initiator mixture is made up of about 60 to 90 wt. % of a partially alkoxylated trifunctional initiator and 10 to 40 wt. % of a secondary partially alkoxylated initiator having an active hydrogen functionality of from 4 to 8. Preferably, the alkylene oxide component to be reacted with the initiator mixture is a blend of ethylene oxide and propylene oxide. Flexible polyurethane foams made from these polyether polyols have improved load bearing properties as compared with those made from prior art polyols.
