    Abstract: The invention relates to the use of copolymers in cleaner formulations for preventing glass from corroding when cleaned in a dishwasher. The copolymers contain: a) 20 to 70 % by weight of at least one monomer component (A) from the group of the monoethylenically unsaturated C3-C10 mono- and dicarboxylic acids or the anhydrides thereof; b) 30 to 80 % by weight of at least one monomer component (B) of the general formula (I), wherein R1, R2 and R3 independently represent H, CH3, C2H5, C3H7, COOH or OH, Y represents -C(=O)- , - C(=O)-O-, -O-, -O-C(=O)-, -O-C(=O)-O- or -C(=O)-NH-, n equals 0 or 1, R4 is either an aromatic or a linear, branched or cyclic aliphatic group with 1 to 6 carbon atoms, and R2 and R4 optionally form together an alkyl moiety with 3 to 6 carbon atoms, which can be optionally substituted by C1-C3 alkyl groups, thereby forming a cycle; c) 0 to 25 % by weight of at least one further monomer component (C) that can be copolymerized with the monomer components (A) and (B) and that is selected from the group consisting of .alpha. olefin s with 10 or more carbon atoms, polyisobutenes with an average of 12 to 100 carbon atoms, Cn-(meth)acrylates wherein n is greater than 6, hydroxy- (meth)acrylates, Cn vinylesters or Cn vinylethers wherein n is greater than 6, acrylnitriles, acrylamides, vinylformamides, allylalcohols, vinylphosphonate s, vinyl-substituted heterocycles and unsaturated organosulfonic acids.

    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.
