ABSTRACT:
A method of preparing polyether polyols in the 200-1000 molecular weight range by modifying a polyol initiator with an epoxy resin and one or more alkylene oxides is described. The modified polyols may be used in preparing rigid isocyanurate foams with improved compressability and flammability properties.
