    Abstract: Polymeric ammonium compounds are disclosed which have a silica-type backbone, comprised of units having the formula: ##STR1## in which R.sup.1 and R.sup.2 represent a group ##STR2## in which R.sup.5 is an alkylene grouping and the free valencies of the oxygen atoms are saturated by silicon atoms of further groups (2), if appropriate with incroporation of crosslinking agents, R.sup.3 and R.sup.4 have the meaning of R.sup.1 and R.sup.2 or represent hydrogen, an alkyl group, cycloalkyl group or the benzyl group, X represents a 1- to 3-valent anion of a protonic acid which forms stable salts with amine bases and x can be a number from 1 to 3. Also disclosed are processes for preparing the polymeric ammonium compounds and to the use of these materials as ion exchange materials.
