The present invention relates to copolymers having a weight average molecular weight (Mw) of 1500 to 75,000, prepared from olefinically unsaturated compounds and containing 0.1 to 4.5% by weight of primary amino groups in the form of structural units corresponding to formula I Image wherein Q is a saturated aliphatic-cycloaliphatic hydrocarbon radical of the type obtained by removing the amino groups from an aliphatic-cycloaliphatic diprimary diamine containing an amino group attached to a primary carbon atom and an amino group attached to a secondary or tertiary carbon atom. The present invention also relates to a process for the production of these copolymers.
