Abstract

See full text

Polyurethane foams are made by curing a reaction mixture that contains an aromatic polyisocyanate, at least one isocyanate-reactive material having an average functionality of at least 2 and an equivalent weight of at least 200 per isocyanate-reactive group, at least one blowing agent, at least one surfactant and at least one catalyst, at least one acetoacetate ester or amide and at least one aminoalcohol or alkylhydroxylamine. Foams so produced emit low levels of formaldehyde, acetaldehyde and propionaldehyde.
