    摘要: 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 fluorinated 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.
