ABSTRACT:
A new and highly useful resin prepolymer blend of (a) polyester polyols prepared by esterifying phthalic anhydride bottoms with aliphatic polyols; (b) aliphatic polyol, (c) compatibilizing polyalkoxylated compound, and (d) (optionally) polyalkoxylated amine or amide diol. This blend can be reacted with organic isocyanates in the presence of fluorocarbon blowing agent and preferably catalysts to produce cellular polymeric structures.
