  • Patent number: 5122587
    Abstract: High molecular weight polyaryletherketones are prepared by nucleophilic polycondensation of a bisphenol with a mixture of a difluoroaromatic and a dichloroaromatic by a process in which, in a first stage, the total amount of bisphenol and dichloroaromatic is added and, in a second stage, the difluoroaromatic is added. The resulting polyaryletherketones have a reduced viscosity of not less than 0.65 and contain from 0.003 to 0.03% by weight of organically bonded chlorine and from 0.003 to 0.03% by weight of organically bonded fluorine.
