BLENDS OF SUCROSE- AND AROMATIC AMINE INITIATED POLYETHER POLYOLS AND THEIR USE IN RIGID POLYURETHANE FOAM MANUFACTURE

摘要

The disclosed invention relates to an isocyanate reaction system having improved capacity for solubilizing hydrocarbon blowing agents. The composition includes a sucrose based polyether polyol and an aromatic amine based polyol. In another aspect, the invention relates to a method of producing a polyurethane foam by reacting an organic polyisocyanate with the polyfunctional isocyanate-reactive composition in the presence of a hydrocarbon blowing agent.
