ABSTRACT:
Terephthalate polyester polyol blends comprising reaction products of a combination of polyethylene terephthalate, a polybasic carboxylic acid compound, a low molecular weight diol compound and a compatibilizer compound are compatible with fluorocarbon blowing agents. These polyol blends are produced by a simple heating process and are thereafter 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.
