Patent ID: 7932310

Claim:
A composition with a two-minute peak heat release, as measured by FAR 25.853, of less than about 80 kW-min/m 2 , the composition comprising a blend of: a) 1 to 99 wt. % of a first resin selected from the group consisting of: polysulfones, polyether sulfones, polyphenylene ether sulfones, and mixtures thereof; b) 0.1 to 10 wt. % of a second resin comprising a silicone copolymer selected from the group consisting of polyimide siloxanes, polyetherimide siloxanes, polyetherimide sulfone siloxanes, polycarbonate siloxanes, polyestercarbonate siloxanes, polysulfone siloxanes, polyether sulfone siloxanes, polyphenylene ether sulfone siloxanes and mixtures thereof; c) 1 to 99 wt. % of a third resin comprising a resorcinol based aryl polyester resin wherein greater than or equal to 50 mole % of the aryl polyester linkages are aryl ester linkages derived from resorcinol, wherein the resorcinol based aryl polyester has the structure shown below: wherein R is at least one of C 1-12 alkyl, C 6 -C 24 aryl, alkyl aryl or alkoxy, n is 0 to 4 and m is at least about 8, or, wherein R is at least one of C 1-12 alkyl, C 6 -C 24 aryl, alkyl aryl or alkoxy, n is 0 to 4, R 5 is at least one divalent organic radical, m is about 4 to 150 and p is about 2-200, wherein the resorcinol based polyester is substantially free of anhydride linkages, wherein the resorcinol based polyester is essentially free of bromine and chlorine d) 0.05 to 2.0 wt % of one or more phosphorus containing stabilizers, selected from the group consisting of phosphites, phosphinates and mixtures thereof, each with a molecular weight above 500 Daltons, and e) 0.01 to 20% by weight of titanium dioxide.
