Abstract: A composition includes specific amounts of an aromatic polycarbonate, a block polycarbonate-polysiloxane, a poly(alkylene terephthalate), a block polyestercarbonate, and an organophosphate ester. Relative to a corresponding composition lacking the block polyestercarbonate, the composition exhibits improved solvent resistance while substantially maintaining impact strength, melt flow, and flame retardancy. The composition is useful for fabricating articles that may come into contact with liquid chemicals or chemical vapors.
