ABSTRACT:
Phthalate polyester polyols comprising reaction products of a phthalic acid compound, a low molecular weight diol compound and a nonionic surfactant compound are provided which are compatibilized with fluorocarbon blowing agents. The polyols are producible by a simple heating process and are blendable with various conventional polyols and other additives to make resin prepolymer blends which can be catalytically reacted with organic isocyanates to produce cellular polyurethanes and polyurethane/polyisocyanurates.
