    Abstract: Use of copolymers obtainable by free-radical copolymerisation of (a) C8-C40-monoolefins with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides in the manner of a mass polymerisation at from 80 to 300 DEG C to form copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and at least partial neutralisation in an aqueous medium with bases of the carboxyl groups formed in the course of the solvolysis and which are present in the form of aqueous dispersions or solutions, as agents for waterproofing leathers and pelt furs.

    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.
