ABSTRACT:
The present invention relates to copolymers prepared from olefinically unsaturated compounds, having a molecular weight (M.sub.n) of 600 to 20,000 and containing 0.1 to 6.0% by weight of secondary amino groups, --NH--, in the form of structural units corresponding to formula I ##STR1## wherein R.sub.1 is a saturated aliphatic hydrocarbon radical containing 2 to 6 carbon atoms, provided that at least two carbon atoms are arranged between the two nitrogen atoms, and
