    Abstract: The invention relates to a thermoplastic moulding composition containing A from 20 to 80% by weight of a thermoplastic polysulphone, B from 10 to 50% by weight of a copolymer based on b1) a vinylaromatic monomer from the group consisting of styrene, alpha -methylstyrene and p-methylstyrene, or mixtures thereof, and b2) acrylonitrile, and C from 10 to 60% by weight of at least one graft copolymer comprising, in each case based on C, c1) from 50 to 90% by weight of at least one elastomer (rubber) and c2) from 10 to 50% by weight of at least one shell grafted onto the elastomer, is characterised in that the copolymer B used contains, based on B, from 88 to 73% by weight of the vinylaromatic monomer b1) and from 12 to 27% by weight of acrylonitrile b2) in copolymerised form, and the viscosity indices are in the range from 50 to 120, and that furthermore, a graft copolymer C having a mean particle size in the range from 80 to 500 nm (d50 value of the cumulative weight distribution) is used whose elastomer c1) contains, in copolymerised form, c11 at least 80% by weight of butadiene and c12 from 0 to 20% by weight of styrene and/or acrylonitrile, and whose shell c2 contains, based thereon, c21 from 90 to 10% by weight of styrene and c22 from 10 to 90% by weight of methyl methacrylate. The moulding composition is used for the production of mouldings.

    Abstract: The catalyst is removed in the preparation of high molecular weight polyphenylene ethers from monohydric phenols, which are alkyl-substituted at the two ortho-positions but not at the para-position and may or may not be alkyl-substituted at the meta-position, by an oxidative coupling reaction with oxygen at from 15 DEG to 50 DEG C. in the presence of a catalyst complex obtained from a copper salt and an organic amine, in the presence of from 1 to 20 parts by weight of a solvent per part by weight of the monomeric phenol, and in the presence or absence of an activator, and removal of the metal component of the catalyst from the polyphenylene ether solution with a complex-forming or chelate-forming compound in aqueous solution, in the presence or absence of reducing and stabilizing substances and assistants for accelerating the interphase reactions and for phase separation, by a method in which the continuous removal of the copper catalyst is carried out in one or more mixer-settler stages at a phase volume ratio of the organic phase to the aqueous phase of from 1:0.1 to 1:1.0, preferably from 1:0.4 to 1:0.6.

    Abstract: The invention relates to a thermoplastic moulding composition comprising: A a copolymer based on ABS, which is formed from an elastomer (rubber) based exclusively on butadiene, onto which a copolymer of a vinylaromatic monomer having 8 to 9 carbon atoms and acrylonitrile has been grafted, and a copolymer (hard matrix) built up from 50 to 90 % by weight of a vinylaromatic monomer having 8 to 9 carbon atoms and from 50 to 10 % by weight of acrylonitrile, and, in each case based on 100 parts by weight of A, B from 200 to 20 parts by weight of a poly(oxamide) having a viscosity index, VI, of from 8 to 80 ml/g which contains the structural unit of the formula (I) as a recurring copolymerised unit in the polymer chain, in which the radical R is a substituted or unsubstituted C2-C25-alkylidene, C5-C30-cycloalkylidene, C2-C80-oxaalkylidene group or a substituted or unsubstituted, monocyclic or polycyclic arylidene group, in which the arylidene radicals may be linked to one another via bifunctional groups. The moulding composition can contain conventional flameproofing agents C and/or a halogen-free component D (synergist for C) and conventional additives E. It is preferably used for the production of mouldings.
