    Abstract: High molecular weight polyphenylene ethers are prepared from monohydric phenols by an oxidative coupling reaction with oxygen in the presence of a catalyst complex obtained from a copper salt and an organic amine by a method wherein the metal component of the catalyst is separated off, after the polymerization, by the addition of a polymeric polycarboxylic acid which is essentially composed of unsaturated monofunctional or difunctional carboxylic acids and/or their anhydrides. Advantageously, the polymeric polycarboxylic acids used are homopolymers or copolymers of (a) from 50 to 100% by weight of one or more unsaturated monofunctional acids of 3 to 10 carbon atoms and/or one or more difunctional acids or their anhydrides of 4 to 6 carbon atoms and from 0 to 50% by weight of one or more monomers which do not possess an acid function and can be copolymerized with (a).

    Abstract: The invention relates to a process for the preparation of polyphenols, in which optionally substituted phenols of the general formula Ph are reacted with polyketones of the general formula [Xm(CO)n]y (I) where X is a (cyclo)aliphatic or aromatic radical and m, n and y are integers between 3 and 30,000, and the ratio between m and n is between 30,000:2 and 3,000:100, in the presence of acidic catalysts to give the polyphenols of the general formula: The optionally substituted phenol used is expediently unsubstituted phenol, p-nitrophenol, p-aminophenol, p-chlorophenol, p-sulphophenol, o-chlorophenol, o-bromophenol, o-methylphenol, O,O-dimethylphenol, o-nitrophenol or o-sulphophenol. X in the polyketone (I) is expediently -CH2-CH2-, -CH=CH-, phenylene or the group, where Z is -O-, -CH2-, -S-, -SO2- or -SO-, m, n and y are expediently integers between 5 and 1,500, the ratio between m and n should be between 15,000:3 and 5,000:50, and y is between 5 and 2,500. At least 2 mole equivalents of the phenol Ph are employed per CO group of the compound (I).

    Abstract: A process for the preparation of block copolymers by polymerising at least one further monomer (B) onto the reactive terminal groups (a2) of existing polymer chains (A), these groups having been produced by supply of energy, in which the reactive terminal groups (a2) are produced, by irradiation with actinic light having a wavelength lambda of from 230 to 450 nm, from terminal groups (a1) which represent photopolymerisation initiators bonded to the polymer chains (A).

    Abstract: A process for depositing metals onto electrically conductive, polymeric carriers, wherein a finely divided metal M having a standard potential Eo of >-2 V is deposited, from a solution of a metal cation compound of the formula (I) Ml'Lm1Ln2Lo3Lp4 (I) where M', L1, L2, L3, L4, l, m, n, o, and p are as defined in the claims, in an aprotic polar or non-polar solvent, onto a polymeric, electrically conductive carrier of the formula (II) [My''(P)]x (II) where M'' is Li, Na, K, Rb or Cs, P is P=-CH-, -C6H4-, -C4H2S-, -C6H4S-, -C4H2O-, -C4H2NH- -C6H4O- or -C5H3N- y is from 0.001 to 0.6 and x is from 5 to 1,000, or onto a polymeric, electrically conductive carrier of the formula (III) [(P)(X)y]x (III) where P is one of the groups listed for formula (II), X is ClO4(-), AsF6(-), PF6(-), SbF6(-), BF4(-), HSO4(-), CF3SO3(-) or Br(-), y is from 0.001 to 0.6 and x is from 5 to 1,000, by reduction, preferably at from -100 DEG to +100 DEG C. The electrically conductive, polymeric systems can be employed in the electrical industry for the production of solar cells, for converting and fixing radiation, and for the production of electric and magnetic switches and electrical storage devices, and can also be used as heterogeneous catalysts and to provide an antistatic finish on 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-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.
