Abstract
Homogenous liquid polyol blend compositions containing (a) certain aliphatic polyols, (b) phthalate diester polyols of said aliphatic polyols, and (c) trimellitate polyols of said aliphatic polyols. Such polyol blend compositions are useful in making homogenous liquid resin prepolymer blends compositions containing, in addition to such a polyol blend, fluorocarbon blowing agent, cell stabilizing surfactant, and urethane and/or isocyanurate catalyst. Such a resin prepolymer blend composition is suitable for reaction with organic isocyanates to produce cellular polyurethane and/or polyisocyanurate polymers.
