Abstract: The invention relates to a liquid preservative for electroplated metal surfaces in the form of aqueous wax dispersions which contain a specific ethylene-acrylic acid copolymer wax comprising from 8 to 25 % by weight of acrylic acid units and from 92 to 75 % by weight of ethylene units in partially or fully neutralised form, in particular the use of this specific ethylene-acrylic acid copolymer wax for preserving electroplated metal surfaces and a process for preserving electroplated metal surfaces.

Abstract: Water-soluble, crosslinked nitrogen-containing condensation products, the viscosity of which, in aqueous solution, increases with increasing temperature, are obtained by reacting a block copolymer of the formula: where R is , n being from 0.75 to 3, , , or , x is from 50 to 250, y is from 20 to 100, the ratio of x to y is from 6.5 to 1 : 15, with compounds having at least four basic NH groups in a weight ratio of from 0.8 : 1 to 30 : 1. The products are added to aqueous systems, e.g. polymer solutions and polymer dispersions, to improve the viscosity characteristics.
