AMINE CONTAINING POLYOLS WITH ENHANCED OXIDATIVE STABILITY
Publication Date: 2004-Nov-18
The IP.com Prior Art Database
Amine initiated polyol (poly alcohol) compositions that exhibit improved heat stability are disclosed. Such compositions comprise a polyol initiated with an amine or polyamine and an antioxidant package capable of inhibiting the high temperature chain cleavage that results when oxidation of the amine occurs. Preferred antioxidant packages include those containing a diphenylamine or a derivative of diphenylamine or a combination of diphenylamine with a phosphite(s), such as tris(nonylphenyl)phosphite. Foams produced from such polyol compositions have improved heat stability at elevated temperatures.
