ABSTRACT:
Urethane prepolymers cured with a blend of an aromatic alkyl diamine and a polyhydric alcohol having more than two hydroxyl groups show excellent compression set and tensile properties. Ratios of diamine to alcohol in the blend, expressed as equivalents, may vary from 1:1 to 19:1, with optimum properties in the elastomer often resulting from blends with the ratio 2:1 to 4:1.
