Abstract (en)

[origin: WO9700902A1] Polyurethane foams having high resilience and significantly improved humid ageing 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 2.5 to 3.0. The polydiene diol is preferably blended with foaming agents prior to addition of the highly reactive polyisocyanate.
