  • Flame retardant aromatic polycarbonate compositions made from fluorinated diphenols
    Patent number: 4379910
    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.

  • Fluorinated diphenols and method for their preparation
    Patent number: 4365098
    Abstract: Fluorinated bisphenols having a fluorinated alkyl group and a hydrogen atom upon the methylene carbon atom are prepared at atmospheric pressure or at low pressures from a phenol reactant and a fluorinated aldehyde compound in the presence of gaseous hydrogen chloride or gaseous hydrogen bromide catalyst. The fluroinated bisphenols having the fluorinated alkyl group and a hydrogen atom upon the methylene carbon atom are produced in excellent yields and are used for making flame-retardant polycarbonates and polyester-carbonate copolymers.

  • Fluorinated monophenols and diphenols and method for their preparation
    Patent number: 4358624
    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.

  • Process for the preparation of substituted guanidines
    Patent number: 4358613
    Abstract: Guanidines are one of the strongest organic bases and find applications where this property is needed, such as in phase transfer catalysis in the form of their substituted derivatives. Their use, however, has been hampered by their expensive nature due to the only mediocre yields in their preparation. The present invention provides a process for the preparation of substituted guanidines in high yields.
