Abstract

Polymeric reaction products are obtained by reacting I) prepolymers obtained from PA1 A) polyoxyalkylenes which have an average molecular weight M.sub.n of from 140 to 10,000 and contain on average from 1.5 to 3.0 PA2 a.sub.1) primary or secondary amino groups or PA2 a.sub.2) epoxy groups per molecule and PA1 B) polymers which are based on conjugated dienes, have an average molecular weight M.sub.n of from 250 to 50,000 and contain on average from 1.5 to 3.0 PA2 b.sub.1) primary or secondary amino groups or PA2 b.sub.2) epoxy groups per molecule, the components (a.sub.1) and ( b.sub.2) or (a.sub.2) and (b.sub.1) being reacted with one another so that from at least an amino equivalent excess to 3 amino equivalents of component (a.sub.1) or (b.sub.1) are present per epoxide equivalent of component (a.sub.2) or (b.sub.2), with PA1 II) at least one compound which forms free radicals.
