    摘要: 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.

    摘要: Impact-resistant thermoplastic molding compositions having a hard component comprising a styrene/acrylonitrile copolymer and a soft component comprising a graft copolymer of styrene and acrylonitrile on a rubbery polymer containing butadiene. The rubbery polymer serving as base for the graft copolymer is produced by polymerization or the monomer of monomers forming said polymer in aqueous emulsion and in the presence of a small amount of an alkanol of from 1 to 4 carbon atoms. The compositions have improved color and color stability and may be processed by conventional methods to form shaped articles.
