Abstract: The invention relates to a degreasing agent for treating skins, fur, limed skins and other intermediate products in leather and fur production, and for treating wool or related protein substances, based on non-ionic surfactants of the alcohol alcoxylate type. Alcohol alcoxylates are used which are obtained by reaction with at least one alcohol ROH with n mols of at least one alkylene oxide per mol of alcohol ROH, wherein R represents an alkyl radical containing between 5 and 30 carbon atoms, and having a main chain which contains between 4 and 29 carbon atoms and is branched in the centre thereof with at least one C1 - C10 alkyl radical; the alkylene oxide comprises between 2 and 6 carbon atoms; and n represents a whole number between 1 and 100. The invention also relates to a method for degreasing skins, fur, limed skins and other intermediate products in leather and fur production, and for treating wool or related protein substances, a degreasing agent according to the present invention being used. The invention further relates to the use of said degreasing agent.

Abstract: The present invention relates to the use of water soluble or water dispersible polymers containing carboxyl groups, optionally in latent form, and side-chains of general formula (I) -X-Y-[-O-(-Alk-O) n -R] k as additives in mineral building materials, wherein X, Y, Alk, R, n and k have the meanings cited in claim 1. Said polymers can be obtained by polymerizing ethylenically unsaturated monomers in the presence of compounds containing phosphorus and, optionally, by additional polymer-analogous transformation. The invention further relates to the production of said polymers and the use thereof. Also described are polymers, which can be obtained by polymerizing aromatic vinyl compounds, olefins, cycloolefins and/or dienes, as D monomers and anhydrides of ethylenically unsaturated dicarboxylic acids as E monomers and which can be used both as parent compounds for the above-mentioned polymers and as additives for mineral building materials.
