Abstract

Polymeric reaction products useful as additions to electrocoating baths are obtainable from PA0 A. a polyoxyalkylene which has an average molecular weight M.sub.n of from 140 to 10,000 and contains on average from 1.5 to 3.0 primary and/or secondary amino groups and PA0 B. a polymer which is based on a conjugated diene, has an average molecular weight M.sub.n of from 250 to 50,000, contains on average from 1.5 to 3.0 epoxy groups per molecule and is obtainable by reacting a hydroxyl- or carboxyl-containing polymer with a glycidyl compound.
