Abstract
Disclosed are active hydrogen compositions comprising: (A) a polyether polyol having a functionality of at least about three; (B) an amine-based polyol having an equivalent weight less than about 250 and derived from the addition of at least two moles of butylene oxide to a nitrogen containing compound having at least two active hydrogen atoms; optionally (C) an active hydrogen containing extender of equivalent weight up to about 200; and optionally (D) a low equivalent weight cross-linking polyol other than (B) above. Also dislcosed are the molded polyurethanes produced from the above compositions and, particularly high strength mat molded reaction injection molded parts.
