    Abstract: Improved flame retardance is imparted to high molecular weight aromatic polycarbonate resins by selecting appropriate fluorinated diphenols and incorporating them in homopolymers or copolymers. The fluorinated diphenols have at least one fluorinated alkyl or fluorinated aryl group upon the methylene carbon atom positioned between the two phenol ring structures. The polycarbonates having improved flame retardance are made from fluorinated diphenols and halogen-containing carbonate precursors. Copolycarbonates having improved flame retardance are derived from the fluorinated diphenols and non-fluorinated diphenols. The flame retardant polycarbonates may be used in films and molded articles where improved resistance to flame is desirable.

    Abstract: Phenol reactants and fluorinated aldehydes or fluorinated ketones are reacted in the presence of organic sulfonic acid catalysts to yield fluorinated monophenols and fluorinated diphenols. Fluorinated monophenols can be isolated and reacted with additional phenol reactant in the presence of organic sulfonic acid catalysts to yield asymmetrical, as well as symmetrical, fluorinated diphenols. A preferred organic sulfonic acid catalyst is methanesulfonic acid. The novel fluorinated monophenols have a hydroxy group and a fluorinated aryl radical or fluorinated alkyl radical substituted upon the benzylic carbon atom. The novel fluorinated diphenols have at least one fluorinated aryl radical or fluorinated alkyl radical substituted upon the methylene carbon atom of the bisphenol.
