Abstract:
A thermoplastic polycarbonate composition comprising: 10 to 30 wt % of a brominated polycarbonate; 10 to 80 wt % of a homopolycarbonate; optionally, 1 to 60 wt % of an aromatic poly(ester-carbonate) comprising carbonate units derived from bisphenol A, resorcinol, or a combination thereof, and ester units derived from a bisphenol, preferably bisphenol A, or resorcinol, and terephthalic acid, isoterephthalic acid, or a combination thereof, wherein a molar ratio of carbonate units to ester units ranges from 1:99 to 99:1; 5 to 15 wt % of a core-shell impact modifier; 1 to 10 wt % of an α,β-unsaturated glycidyl ester copolymer impact modifier; 0.01 to 1 wt % of a hydrostabilizer, preferably an epoxy hydrostabilizer; optionally, 0.1 to 10 wt % of an additive composition; wherein the wt % of each component is based on the total weight of the composition, which totals 100 wt %.
