Abstract of the Disclosure: Homo- co- and/or block polymers which are modified with amino functional groups, are obtained from vinylaromatics and/or dienes and contain functional groups of the formulae (I) to (VI) (I) (II) (III) Image (IV) (V) (VI) where N is nitrogen, R1 and R4 are each hydrogen, alkyl, cycloalkyl or aryl, R2, R3 and R5 are each alkyl, cyclo- alkyl or aryl, Me is an alkali metal and A is an unsub- stituted or substituted bridge which, in addition to carbon, may contain N or O members, a process for the preparation of the polymers from living anionically poly- merized or alkali-metal-metallized homo-, co- and/or block copolymers from vinylaromatics and/or dienes, which are reacted with appropriate nitrogen compounds in the presence of a polar or nonpolar solvent, and the conver- sion of the polymers as claimed in claim 1 for the pre- paration of similar polymers by hydrolysis, alcoholysis and/or hydrogenation.
