CA 2546299

Provided are new flames retardants and liquid flame retardant additive compositions of low viscosity for use in flexible polyurethane foams. The new flame retardants are the reaction product of at least one brominated aromatic diester diol with at least one alcohol-reactive agent. Preferred liquid flame retardant additive compositions are capable of minimizing visible scorching of the foam during its production. Flexible flame retardant polyurethane foams and methods for their production are also provided. The flame retardant additive compositions are formed at least from (a) at least one reaction product of a brominated aromatic diester diol and an alcohol-reactive agent; (b) at least one hindered amine antioxidant; and (c) at least one phenolic antioxidant in which the phenolic ring is substituted by an alkanoic acid alkyl ester group in which alkanoic acid moiety has in the range of 2 to about 4 carbon atoms and the alkyl group has in the range of 6 to 16 carbon atoms.

L'invention porte sur de nouveaux produits ignifuges et sur des additifs liquides ignifuges, de faible viscosité, utilisés dans la fabrication de mousses souples de polyuréthane. Les nouveaux produits ignifuges sont les produits de réaction d'au moins un diester de diol aromatique bromé et d'un agent réagissant à l'alcool. Les additifs liquides ignifuges préférés sont capables de réduire le grillage visible de la mousse pendant sa fabrication. L'invention porte également de mousses souples de polyuréthane et leurs procédés de fabrication. Les additifs ignifuges comportent au moins: (a) un produit de réaction d'un diester de diol aromatique bromé et un agent réagissant à l'alcool; (b) un antioxydant d'amine empêchée; et (c) un antioxydant phénolique dont le cycle phénolique est substitué par un groupe d'ester alkylique de l'acide alcanoïque dans lequel le fragment d'acide alcanoïque présente de 2 à environ 4 atomes de carbone, et le groupe alkyle de 6 à 16 atomes de carbone.
