ABSTRACT:
Phthalate polyester polyols comprising reaction products of a phthalic acid compound, a low molecular weight diol compound and a hydrophobic compound and a nonionic surfactant compound are provided which are compatible with fluorocarbon blowing agents and which possess a variety of other desirable characteristics. 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.
