ABSTRACT:
Homopolymers, copolymers and/or block copolymers which are obtained from vinylaromatics and/or dienes, are modified with functional amino groups and contain functional groups of the formula (I) or (II) ##STR1## where N is nitrogen, R.sup.1 and R.sup.2 are each alkyl or aryl, A is an unsubstituted or substituted one-membered carbon bridge, Me is an alkali metal and B is a 2-membered to 12-membered carbon bridge in which at least the members adjacent to the nitrogen atoms consists of --C(R.sup.3,R.sup.4) radicals, where R.sup.3 and R.sup.4 can be identical or different and are each hydrogen, alkyl, cycloalkyl or aryl, and the more remote members can be not only --C(R.sup.3 R.sup.4) radicals but also ether or N-alkyl- or N-arylimino groups, a process for the preparation of the polymers from the corresponding living anionically polymerized polymers, or polymers metallized with an alkali metal, and the coresponding hydrazine derivatives, and the use of the polymers for the preparation of similar polymers possessing functional groups of the general formula (V) or (VI) ##STR2## by reaction with an equivalent amount of water, or of similar polymers possessing the functional groups of the general formula (VII) or (VIII) ##STR3## by reaction with an excess of water.
