Abstract: The present disclosure relates to articles formed from polycarbonate prepared according to a melt polymerization method wherein. An article prepared by a process comprising the steps of: forming a polycarbonate resin via melt transesterification; mixing a flame retardant component to form a composition, wherein the mixing is accomplished as an online operation; and forming the article from the composition, wherein the article achieves a better flame rating than a comparative article formed from a substantially identical reference composition comprising the same loading of the polycarbonate resin and the flame retardant component, but a mixing of the polycarbonate resin and the flame retardant component of the substantially identical reference composition is accomplished as an offline operation.
