    摘要： Aminoalkyl-substituted organopolysiloxane thioureas are disclosed which consist of the units ##STR1## whereby R.sup.1 stands for a group ##STR2## R.sup.5 is an alkylene grouping, R.sup.2 is equal to R.sup.1 or H, R.sup.3 is equal to R.sup.1 or H or a group (CH.sub.2).sub.n --N(R.sup.6).sub.2 (III) (in which n=1-6, R.sup.6 =H or an alkyl group with C.sub.1 -C.sub.5) and R.sup.4 =H or a group of the formula (III), whereby (I) contains at most 2 (III) groups and at most 2 (III) groups and the free valances of the oxygen atoms sitting on the silicon atom are saturated by silicon atoms of other (III) groups, optionally with the insertion of cross-linking agents containing Si, Ti or Zr. The compounds can be random copolycondensates, block copolycondensates or mixed copolycondensates in relation to the optionally present cross-linking agents. In addition, various methods of preparing the compounds are indicated. The compounds can be used especially for the removal of dissolved metals from aqueous or organic phases.
