    摘要: The present invention relates to an aqueous antifreeze composition comprising 10 to 50% by weight of one or more dicarboxylic acids, preferably aliphatic dicarboxylic acids having 4 to 12 carbon atoms in the form of the alkali metal, ammonium or alkaline earth metal salt. Preferably, these salts are used in combination with at least one further substance. This gives antifreeze compositions with a good frost protective action, good heat conductivity and good protection against corrosion.

    摘要: The invention relates to a composition for the treatment of metal surfaces and to the deposition of metals or metal alloys on plastics surfaces, comprising a) at least one polymer as component A, composed of an amino-containing polymer (component Aa), at least one aromatic compound (component Ab), and, where appropriate, an aldehyde (component Ac); b) water or another solvent suitable for dissolving, dispersing, suspending or emulsifying the polymer, as component B; c) if desired, surface-active compounds, dispersants, suspension media and/or emulsifiers as component C. The invention further relates to a process for the treatment of a metal surface and also to a process for the deposition of metals or metal alloys on a-plastics surface in which the metal or plastics surface is contacted with a polymer (component A). The invention further relates to the use of polymers (component A) for the treatment of metal surfaces and for the deposition of metals or metal alloys on a plastics surface, and to polymers composed of specific components A′a, Ab and A′c.
