    Abstract: Transparent flame-retardant poly(arylether-arylsulfone) molding materials preferably contain not less than 50% by weight of units of the formula and, as a flameproofing agent, from 0.1 to 10% by weight, based on the weight of poly(arylether-arylsulfone), of a poly(2,6-dibromophenylene 1,4-oxide) having a molecular weight of from 1000 to 20000, and, if required, a heat stabilizer. The molding materials are useful for the production of shaped articles, films and fibers.

    Abstract: O.Z. 0050/034810 A process for the preparation of electrically conductive polymers which are stable to air and have conductivities greater than 1 x 10-3 S/cm, by reacting a cation of a metal of group VII or VIII or of sub-group I of the periodic table with an organic chelating compound to give a metal chelate and oxidizing the latter to form a polymer, wherein the organic chelating compound is a 1,9-substituted phenalene of the general formula I , where X is 0, NH, S, Se or Te and Y is OH, NH2 or SH. The electrically conductive polymers are useful for the production of solar cells, the conversion and fixing of radiation, the production of electrical and magnetic switches and the antistatic treatment of plastics.

    Abstract: High molecular weight polyphenylene ethers are prepared from monohydric phenols by an oxidative coupling reaction with oxygen in the presence of a solvent and of a catalyst complex consisting of a copper salt and an organic amine of the general formula where R1 is C2-C20-alkylidene, preferably C2-C12-alkylid-ene, or alkenylidene, R2 is H or C1-C12-alkyl, preferably C1-C4-alkyl, or C5-C8-cycloalkyl, each of which is unsubstituted or substituted by functional groups, and n is an integer from 1 to 4, preferably 1 or 2. Preferred functional groups are -OR3, -NHR3 or -SR3, in which R3 is H C1-C12-alkyl or C5-C8-cycloalkyl, and the most suitable amines are 3-tert.-butoxypropylamine, 4-tert.-butoxy-butylamine, 3-tert.-butoxy-2-methylpropylamine, 3-tert.-butoxy-2,3-dimethylpropylamine, 3-tert.-butoxy-2-methyl-octylamine and N-methyl-N-(4-tert.-butoxybutyl)-amine. The polyphenylene ethers can be processed to moldings by a thermoplastic method.
