Abstract: Described is the use, as water-treatment agents, of water-soluble graft polymers obtained by the radical-initiated polymerization of (A) monomer mixtures containing as monomers monoethylenically unsaturated carboxylic acids, their alkali-metal salts and/or their ammonium salts, in the presence of (B) monosaccharides, oligosaccharides, polysaccharides, oxidatively, hydrolytically or enzymatically degraded polysaccharides, chemically modified mono-, oligo- or polysaccharides, or mixtures of these compounds, in the ratio, by mass, of A:B of (95 to 20):(5 to 80).

Abstract: 1. A glycol-based coolant mixture which is free of nitrites and phosphates, containing a) 1 - 5% by weight of an alkali metal salt of acid II see diagramm : EP0283806,P7,F1 where R is a -CH2 -, see diagramm : EP0283806,P7,F2 see diagramm : EP0283806,P7,F3 or CH2 CH2 CH2 group, b) 0.1 - 1% by weight of a silicate of the general formula III (MO)q SiO4-q/2 where M is an alkali metal and q is from 0.4 to 4, c) 0.01 - 0.2% by weight of a silicate stabilizer, d) 0 - 0.5% by weight of an alkali nitrate, e) 0.05 - 0.2% by weight of benzotriazole or tolutriazole, f) 0.5 - 2% by weight of borax, and g) 0.05 - 1% by weight of NaOH, all the percentages being based on the glycol present in the coolant mixture.
