ABSTRACT:
Fluorocarbon blowing agent compatible polyol blends are provided comprising reaction products of a combination of (a) a residue from the manufacture of dimethyl terephthalate, (b) a low molecular weight diol compound, (c) a nonionic surfactant compound, (d) optionally a hydrophobic compound, and (e) optionally a polybasic carboxylic acid compound. These polyol blends are produced by a simple heating process and are thereafter optionally blendable with various conventional polyols and other additives (including fluorocarbons and catalysts) to make resin prepolymer blends. Such resin blends can be catalytically reacted with organic isocyanates to produce cellular polyurethanes and polyurethane/polyisocyanurates.
