    Abstract: Disclosed is the use of highly functional, highly branched or hyperbranched polycarbonates as a dispersing agent for pigments. Said polycarbonates can be obtained by a) producing one or several different condensation products (K) by a1) reacting at least one organic carbonate (A) of general formula RO[(CO)O]nR with at least one aliphatic, aliphatic/aromatic, or aromatic alcohol (B) comprising at least 3 OH groups while eliminating alcohols ROH, R independently representing a linear or branched aliphatic, aromatic/aliphatic, or aromatic hydrocarbon radical containing 1 to 20 C atoms, and radicals R being optionally interconnected so as to form a ring containing the grouping -O[(CO)O]n-, and n representing an integer ranging from 1 to 5, or a2) reacting phosgene, diphosgene, or triphosgene with the aliphatic, aliphatic/aromatic, or aromatic alcohol (B) while releasing hydrogen chloride, the quantitative ratio between alcohols (B) and the carbonates (A) or the phosgenes in the reaction mixture being selected such that the condensation products (K) on average are provided with one carbonate group or carbamyl chloride group and more than one OH group or one OH group and more than one carbonate group or carbamyl chloride group, and b) intermolecularly reacting the condensation products (K) obtained in step a).

    Abstract: Disclosed is a method for producing leather, which is characterized in that pelts, pickled pelts, or semifinished products are treated with at least one polymer that can be obtained by copolymerizing (A) at least one ethylenically unsaturated monocarboxylic acid or dicarboxylic acid comprising 3 to 8 C atoms or at least one anhydride derived from a monocarboxylic acid or dicarboxylic acid comprising 3 to 8 C atoms, (B) at least one vinyl aromatic compound, (C) at least one alkoxylated unsaturated ether of general formula (I), (D) optionally, additional monoethylenically unsaturated monomers. The variables in formula (I) are defined as follows: R , R , R are identical or different and are selected among C1-C4 alkyl or hydrogen; R , R are identical or different and are selected among C1-C4 alkyl or hydrogen; R is selected among hydrogen, SO3M, PO3M2, C1-C30 alkyl, -CO-H (formyl), CO-C1-C20 alkyl, -CO-C6-C14 aryl; M represents alkali metal, NH4 , or CH3; n represents an integer between 3 and 100; and y represents an integer between 0 and 10.
