ABSTRACT:
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) ##STR1## where N is nitrogen, R.sup.1 and R.sup.4 are each hydrogen, alkyl, cycloalkyl or aryl, R.sup.2, R.sup.3 and R.sup.5 are each alkyl, cycloalkyl or aryl, Me is an alkali metal and A is an unsubstituted 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 polymerized 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 conversion of the polymers as claimed in claim 1 for the preparation of similar polymers by hydrolysis, alcoholysis and/or hydrogenation.
