Compounds which contain one or more groups of the formula (I) n —CH 2 —CH(NR 1 R 2 )— (I) n where n R 1 and R 2 , independently of one another, are each hydrogen, C 1-20 -alkyl, C 6-18 -aryl, C 7-20 -alkaryl, C 7-20 -aralkyl or a polyamine radical, n are prepared by reductive amination of compounds which contain one or more groups of the formula (II) n —CH 2 —CH(O—C(O)—R 3 )— (II) n where n R 3 is hydrogen, C 1-20 -alkyl, C 6-18 -aryl, C 7-20 -alkaryl or C 7-20 -aralkyl, with amines of the formula (III) n HNR 1 R 2 (III) n and hydrogen. |
