Abstract
This invention relates to stabilizing isocyanate-reactive compositions containing flame retardants by the use of certain tertiary amines or ammonium compounds, in which said stabilized compositions are prepared by mixing PA1 (a) at least one isocyanate-reactive compound having a molecular weight of 400 to 10,000 and a functionality of 2 to 7; PA1 (b) at least one isocyanate-reactive compound having a molecular weight of less than 399 and a functionality of 2 to 6; PA1 (c) at least one (i) isocyanate-reactive tertiary amine polyether, (ii) fatty amido-amine, and/or (iii) ammonium salt derivative of a fatty amido-amine; PA1 (d) a flame retardant; PA1 (e) a catalyst; and PA1 (f) optional additives. This invention also relates to urethane-based products prepared by reaction of organic polyisocyanates with such compositions.
