ABSTRACT:
Polyurethane foams having high resilience, significantly improved humid aging, excellent tear strength, and light color are formed from a polydiene diol, preferably a hydrogenated polybutadiene diol, having a hydroxyl functionality from 1.6 to 2.0 and from an aromatic polyisocyanate having an isocyanate functionality of from 1.8 to 2.5. The polydiene diol is preferably blended with foaming agents prior to addition of the highly reactive polyisocyanate.
