Abstract: A process is disclosed for preparing polymers with hydroxamic acid, hydroxamic acid ether and/or hydrazide groups in the side chain, by reacting (a) polymers which contain ester, amide, imide and/or acetal groups in the main chain and carboxyl, ester, imide, amide and/or anhydride groups and/or halogen as side chain, or a polysuccinimide with (b) hydroxylamine, hydroxylamine alkyl ethers with 1 to 18 C atoms in the alkyl group, N-monoalkylhydroxylamines with 1 to 18 C atoms in the alkyl group and/or in salts of said compounds and/or (c) hydrazine and/or hydrazine salts in an aqueous medium or alcohols at pH values of at least 7. Also disclosed is the use of the thus obtained modified polymers as additives to washing and cleaning agents, as complexing agents for alkaline earth and heavy metal ions, as pigment dispersants and as scale inhibitors.

Abstract: Single or multi-nuclear metal complexes [LnMmXp] Y, in which M is manganese in the oxidation number (II, III, IV, V and/or VI), copper in the oxidation number (I and/or II), cobalt in the oxidation number (II and/or III) or zinc in the oxidation number (II), X is a co-ordination or bridge group, Y is a counter-ion in the corresponding stoichiometric quantity for compensating a charge z, in which z may be positive, zero or negative as the charge of the metal complex, n and m are mutually independently whole numbers from 1 to 8, p is a whole number from 0 to 32 and L is certain nitrogen and/or oxygen atoms as co-ordination centres-containing organic molecules as ligands. The metal complexes (I) are suitable as bleaching and oxidation catalysts, especially in washing and cleaning agents and in textile and paper bleaching.
