ABSTRACT:
Disclosed is a thermoplastic composition comprising a polycarbonate terpolymer comprising structures derived from structures (I), (II) and (III), wherein (I) is a dihydroxy compound having the structure (A):wherein n is 0 to 4 and Rfis independently a halogen atom, a C1-10hydrocarbon group, or a C1-10halogen substituted hydrocarbon group; (II) comprises a second dihydroxy compound derived from Formula (A) and different from (I) and wherein n and Rfare as previously defined; and (III) a third dihydroxy compound not derived from Formula (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 and wherein said polycarbonate terpolymer is amorphous; an impact modifier; and an ungrafted rigid copolymer. The thermoplastic composition has improved chemical resistance and scratch resistance.
