Abstract

Modified homopolymer, random copolymers and/or block copolymers of aromatic vinyls and/or dienes contain functional groups of the general formula (I): ##STR1## where N is nitrogen, O is oxygen, Y is a substituted or unsubstituted bridge which besides carbon additionally contains N- or O-members, R is any desired organic radical, R.sup.1 is hydrogen, alkyl, cycloalkyl or aryl, and n is a whole number greater than or equal to 1, are prepared from living anionically polymerized or from alkali metallized homopolymers, random copolymers and/or block copolymers of aromatic vinyls and/or dienes which, reacted with organic nitrogen compounds, have a nitrogen-alkali metal bond by reaction of polymers of the general formula (II) in the presence of a polar or apolar solvent with compounds of the general formula (III) where Me is an alkali metal, X is halogen and Y, O, N, R, n and R.sup.1 (other than hydrogen) have the abovementioned meanings ##STR2##
