Patent ID: 7084196

Claim:
A flame retardant composition which comprises (A) a polymer substrate, and (B) an effective flame retarding amount of a synergistic mixture of (i.) at least one compound selected from the group consisting of (a) nitroxyl stabilizers (d) substituted hydroxylamine stabilizers of the formula (IIIb) or (IIIa) wherein T 1 is straight or branched chain alkyl of 1 to 36 carbon atoms, cycloalkyl of 5 to 12 carbon atoms, aralkyl of 7 to 9 carbon atoms, or said aralkyl substituted by one or two alkyl of 1 to 12 carbon atoms or by one or two halogen atoms; T 2 is hydrogen, or independently has the same meaning as T 1 ; and T 3 is allyl, straight or branched chain alkyl of 1 to 36 carbon atoms, cycloalkyl of 5 to 18 carbon atoms, cycloalkenyl of 5 to 18 carbon atoms or a straight or branched chain alkyl of 1 to 4 carbon atoms substituted by phenyl or by phenyl substituted by one or two alkyl groups of 1 to 4 carbon atoms or by 1 or 2 halogen atoms; and (ii.) at least one compound selected from the group consisting of brominated flame retardants, phosphorus containing flame retardants and inorganic flame retardants and where component (i.) is present from 0.25 to 10% by weight, based on component (A).
