- 17 - O.Z 0050/37904 Abstract of the Disclosure: 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) Image Image or (I) (II) where N is nitrogen, R1 and R2 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 adja- cent to the nitrogen atoms consist of -C(R3,R4) radicals, where R3 and R4 can be identical or different and are each hydrogen, alkyl, cycloalkyl or aryl, and the more remote members can be not only -C(R3R4) radicals but also ether or N-alkyl- or N-arylimino groups, a process for the pre- paration of the polymers from the corresponding living anionically polymerized polymers, or polymers metallized with an alkali metal, and the corresponding hydrazine derivatives, and the use of the polymers for the prepara- tion of similar polymers possessing functional groups of the general formula (V) or (VI) Image Image or (V) (VI) by reaction with an equivalent amount of water, or of similar polymers possessing the functional groups of the general formula (VII) or (VIII) Image Image or (VII) (VIII) by reaction with an excess of water.
