Abstract: High molecular linear, thermoplastic, epoxide-amine-adducts containing the structural segment ##STR1## are prepared by a solvent-free reaction of equivalent amounts at 20 to 200.degree. C. of N,N'-bis(aralkyl) diamines (for example, N,N'-dibenzyl-ethylenediamine, N,N'-dibenzyl-p-xylylenediamine, N,N'-dibenzyl-4,4'-diamino-diphenylmethane, N,N'-dibenzyl-3,6-dioxa-octanediamine-1,8) with diepoxides (for example, 2,2-bis(4-glycidyloxyphenyl)propane). The polyadducts are soluble and may be processed by thermoplastic methods. The polyaddition process may be conducted for the forming of shaped objects in a form-shaping vessel, for the production of coatings directly upon the surface to be coated and also in the presence of inserted materials and has, due to these characteristics, the nature of a casting system.
