Abstract
A composition includes specific amounts of a polyester with 1,4 cyclohexanedimethylene terephthalate repeat units, a halogen-free aromatic polycarbonate, a brominated aromatic polycarbonate, and an unsubstituted or substituted C2 C18 hydrocarbyl sulfonate salt. The composition exhibits an improved balance of flame retardancy and transparency relative to a corresponding composition without the sulfonate salt. The composition can be used to fabricate articles that benefit from its transparency and flame retardancy
