USE OF MONOHYDRIC ALCOHOLS IN MOLDED POLYURETHANE RESINS

摘要

Disclosed are novel active hydrogen compositions comprising: (1) a polymeric polyol; (2) a low equivalent weight cross-linking polyol; (3) optionally a second polyol having an equivalent weight up to 500; and (4) a sufficient amount of a monohydric alcohol of equivalent weight up to 1,500 to provide a monophase low viscosity blend. Also disclosed are the molded polyurethanes produced from the above compositions, and, particularly high strength mat molded reaction injection molded parts, and the process of preparing such molded polyurethanes and parts.
