ABSTRACT:
Organosiloxane amine copolycondensates as statistic or block copolycondensates or mixtures thereof consisting of the units ##STR1## in which R.sup.1 to R.sup.5 is ##STR2## and R.sup.6 is bound directly to the nitrogen atom or the double-bonding X group and is alkylene, cycloalkylene or ##STR3## in which n is 1 to 6 and m 0 to 6. The free valences of the oxygen atoms bound to the silicon atom are saturated by silicon atoms of further groups of formula III, optionally with the inclusion of cross-linking agents, X stands for ##STR4## in which R" is H or alkyl. In addition, preparation methods and the use of the products for the removal of dissolved metals from liquid phase or for the adsorption of gaseous compounds.
