DISPERSION OF SULFONATE GROUP-CONTAINING POLYMER, MANUFACTURE AND USE AS COATING AGENT

The present invention is directed to aqueous dispersions having a solid content of at least about 10% by weight of polymers containing from about 0.1 to 6% by weight of incorporated sulphonate groups, characterized in that cations of at least divalent metals, silver or monovalent copper are present...

Beschreibung
Zusammenfassung:	The present invention is directed to aqueous dispersions having a solid content of at least about 10% by weight of polymers containing from about 0.1 to 6% by weight of incorporated sulphonate groups, characterized in that cations of at least divalent metals, silver or monovalent copper are present in the dispersions as counterions to the chemically-incorporated sulphonate anions to at least about 80 equivalent percent, based on the total quantity of the cations present. Another object of this invention is a process for the production of such aqueous dispersions which is characterized in that aqueous dispersions having a solid content of at least about 10% by weight, of polymers containing from about 0.1 to 6% of incorporated sulphonate groups, in which alkali metal cations or monovalent ammonium cations are present as counterons, are treated with a cation exchanger which is charged with cations of the above-mentioned type. A final object of this invention is the use of the dispersions according to the invention as coating agents in a coating operation for flexible or rigid substrates.
