We have been able to show repeatedly that cationic alkaline hydrogels based on diallyldimethylammonium hydroxide (DADMAOH) in particular can be used effectively to seal water-bearing cracks or as coupling media for electrochemical chloride extraction. Upscaling is a challenge, as commercial cation-selective membranes have proven to be less effective here. On the other hand, neutral gels and gel particles can be easily prepared from diallyldimethylammonium chloride (DADMAC) in large quantities and with a wide range of compositions. Here it is shown that these neutral gel particles can be converted into DADMAOH particles with residual halide contents of &lt;0.3 % by means of inverse static anion exchange in NaOH solution. The physical and chemical properties of the alkaline particles correspond to those of the alkaline gels and fulfill all necessary requirements for building material applications, but are much easier to produce.<\/p>\n<p>T.
