Patent ID: 8871865

Claim:
A thermoplastic composition comprising: a polycarbonate terpolymer comprising structures derived from at least one of each of structures (I), (II) and (III), wherein (I) is a dihydroxy compound having the structure (A): wherein n is 0 to 4 and R f is independently a halogen atom, a C 1-10 hydrocarbon group, or a C 1-10 halogen substituted hydrocarbon group; (II) comprises a second dihydroxy compound derived from Formula (A) and different from (I) and wherein n and R f are as previously defined; and (III) a third dihydroxy compound, wherein the third dihydroxy compound is bisphenol A, wherein the sum of the mol percent of all of structures (I) and (II) is greater than 45% relative to the sum of the molar amounts of all of structures (I), (II) and (III) in the polycarbonate terpolymer, the ratio of dihydroxy compounds (I):(II):(III) is about 1:1:1, and wherein the polycarbonate terpolymer is amorphous; an impact modifier; an ungrafted rigid copolymer; and a phosphorous containing flame retardant.
