Condensation products comprised of carboxylic acid dianhydrides, diamines or polyamines, especially polyoxyalkylene amines and polyphenolene or aminophenolene are suited as structural constituents for epoxide resin compositions. In addition, these compositions contain conventional rubber- modified epoxide resins and liquid and/or solid polyepoxides and conventiona l hardeners and accelerators, and they optionally contain fillers and rheology auxiliary agents. The inventive compositions are suited as impact-resistant, impact-peel-resistant and peel-resistant adhesives used in vehicle manufacturing and in electronics. These adhesives exhibit very good impact- peel characteristics, especially at very low temperatures.
