Abstract
Process for obtaining poly (arylamines) having methylenic bridges and which have been prepared by reaction of arylamines and formaldehyde in the presence of acids and water, by exchange for starting arylamines, characterized in that aqueous solutions of poly (arylamine) salts, in concentrations that form an at least partially heterogeneous system (with two phases) starting with arylamines, they are mixed with starting arylamines in co-current or countercurrent and then separated from them, whereby ions of poly (arylamine) salts are exchanged. ) by starting arylamines containing hydroxy groups, and, on the one hand, poly (arylamines) and, on the other hand, aqueous solutions of the starting arylamine salts are obtained.
