    Abstract: A self-extinguishing thermoplastic moulding composition containing a copolymer A formed from a butadiene-based elastomer onto which a copolymer of a vinylaromatic monomer having 8 to 9 carbon atoms and acrylonitrile has been grafted, and a copolymer (hard matrix) comprising a vinylaromatic monomer having 8 to 9 carbon atoms and acrylonitrile (ABS), and furthermore containing, in each case based on 100 parts by weight of A, from 2 to 40 parts by weight of brominated polyphenylene ethers, which are known per se, contain a free OH end group and have mean molecular weights (number average) in the range from 2000 to 20000, as flameproofing agent B and from 0.5 to 20 parts by weight of a metallic or non-metallic compound (synergist) C. The moulding composition may contain conventional additives and is used to produce mouldings.

    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-alkylidene, 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.-butoxybutylamine, 3-tert.-butoxy-2-methylpropylamine, 3-tert.-butoxy-2,3-dimethylpropylamine, 3-tert.-butoxy-2-methyloctylamine and N-methyl-N-(4-tert.-butoxybutyl)-amine. The polyphenylene ethers can be processed to moldings by a thermoplastic method.

    Abstract: A halogen-free flameproofed thermoplastic molding material consists of a halogen-free thermoplastic resin (A) and one or more further halogen-free components. The thermoplastic resin (A) is present in an amount of from 30 to 90% by weight, based on the molding material. The latter contains, as further components, from 1 to 50% by weight of a phenol/aldehyde resin (B), from 1 to 50% by weight of a nitrogen-containing organic compound (C) and from 3 to 50% by weight of a phosphorus-containing organic compound (D), the percentages in each case being based on the molding material. The molding material is used for the production of flameproofed moldings.
