摘要

Process for the production of leather, leather, use of a leather, garment, furniture, car accessories, polu00ecmero, process for the preparation of polu00ecmeros, and aqueous dispersion.It is described a method for producing leather, which is characterized by the fact that the skins.Skins in brine or semi-finished products are treated with at least one polymer that can be obtained copolimerizandose (a) at least one monocarboxylic acid, unsaturated acid or acid.Containing 3 to 8 carbon atoms or at least one derived from a polyether acid anhydride or acid acid containing 3 to 8 carbon atoms.(b) at least one vinyl aromatic compound, (c) at least one unsaturated ether alcoxilado of general formula (I), (d) optionally additional monomers monoetilenicamente unsaturated.The variables of the formula (I) are defined as follows: ru00ac 1u00ac, ru00ac 2u00ac, ru00ac 3u00ac are identical or different and are selected between C ~ 1 ~ C ~ 4 ~ alkyl or hydrogen; ru00ac 4u00ac,Ru00ac 5u00ac are identical or different and are selected between C ~ 1 ~ C ~ 4 ~ alkyl or hydrogen; ru00ac 6u00ac is selected among hydrogen, so ~ 3 ~ m, Po ~ 3 ~ m ~ 2 ~ C ~ 1 ~ C ~ 30 ~ alkyl, - co - H (formila)Co - C ~ 1 ~ C ~ 20 ~ alkyl, - co - C ~ 6 ~ C ~ 14 ~ arila; m is alkaline metal, NH ~ 4 ~ n + n or CH ~ 3 ~; n represents an integer of between 3 and 100; and Y is an integer between 0 and 10.
