    摘要： Tanning agents can be prepared by reacting at least one aldehyde of formula I, with at least one further identical or different aldehyde of formula I, where Z is a single chemical bond, unsubstituted or substituted C1-C12-alkylene, unsubstituted or substituted C5-C12-cycloalkylene or unsubstituted or substituted C6-C14-arylene, the reaction being carried out in the presence of an acidic catalyst and in the presence of at least one further carbonyl compound of formula II where R1 to R4, independently of one another, are hydrogen, unsubstituted or substituted C1-C12-alkyl, unsubstituted or substituted C3-C12-cycloalkyl, unsubstituted or substituted C7-C13-aralkyl or unsubstituted or substituted C6-C14-aryl, with the proviso that, where Z is a single chemical bond or a radical without a-hydrogen atoms, at least one further aldehyde of the formula I, in which Z contains α-hydrogen atoms, or at least one further carbonyl compound of formula II is present.

    摘要： Aqueous dispersions of copolymers are obtainable by free radical copolymerization of (A) at least one ethylenically unsaturated dicarboxylic anhydride, derived from at least one dicarboxylic acid of 4 to 8 carbon atoms, (B) at least one oligomer of branched or straight-chain C3-C10-alkene, at least one oligomer having an average molecular weight Mn of from 300 to 5 000 g/mol or being obtainable by oligomerization of at least 3 equivalents of C3-C10-alkene, (C) optionally at least one ethylenically unsaturated comonomer differing from (A), and optionally reaction with (D) at least one compound of the formula I a or I b and subsequent addition of water, where, in formulae I a and I b, A1 are identical or different C2-C20-alkylene, R1 is linear or branched C1-C30-alkyl, phenyl or hydrogen, and n is an integer from 1 to 200, the water content being from 30 to 99.5% by weight, based on aqueous dispersion.
