Abstract
Catalyst compositions useful in the production of low or no amine emission flexible polyurethane foam as well as rigid insulating polyurethane foam produced with systems containing polyether, polyester, Mannich polyols as well as organic-halogen containing flame retardants and blowing agents, are disclosed. The catalysts are characterized by the presence of amine compositions containing unsaturated aliphatic substituent together with secondary hydroxyl groups able to bind to polyurethane polymers and render a low odor and no or low amine emissions finished product.
