<p>Polyester-carbonate copolymers, blends of polyesters with polyester-carbonate copolymers and block copolymer compositions of polyester-carbonate copolymers have improved flame retardance when portions of the copolymer contain fluorinated diphenol copolymer. The fluorinated diphenol has at least one fluorinated alkyl or fluorinated aryl group upon the methylene carbon atom positioned between the aromatic ring structures of the diphenol. Polyester-carbonate copolymers, the blends of polyesters with the polyester-carbonate copolymers and block polymer compositions of polyester-carbonate copolymers are flame retardant.</p> |
