ABSTRACT:
Polymeric tertiary and secondary amines as described with a silica-type backbone, comprising units of the formula: ##STR1## in which R.sup.1 and R.sup.2 represent a group ##STR2## R.sup.4 is alkylene and the free valencies of the oxygen atoms are saturated by silicon atoms of further groups (2), if appropriate with incorporation of crosslinking agents, R.sup.3 has the same meaning as R.sup.1 and R.sup.2, or it represents hydrogen, alkyl, cycloalkyl or benzyl. Also disclosed are processes for preparing the polymeric tertiary and secondary amines and the use of these materials for removing acids from liquids and gases.
