Abstract:
This invention relates to polyurethane foams which exhibit decreased aldehyde emission, to a process of preparing these polyurethane foams, and to a method of decreasing aldehyde emissions in foams. The polyurethane foams herein additionally comprise a small quantity of a polyhydrazodicarbonamide dispersion polyol to the isocyanate-reactive component, or a trimerized hexamethylene diisocyanate to the polyisocyanate component.
