Abstract

The invention relates to multi-amine functional oligomers and multi-oxime functional oligomers in addition to a method for producing the same by means of the co-polymerization of carbonyl carriers such as olefins or dienes, reaction with hydroxylamine and a subsequent selective catalytic hydrogenation.
