摘要： Saturated polyesters containing terminal carboxyl groups and, per molecule, at least one side chain, containing imide groups, of the formula I ##STR1## in which R.sup.1 and R.sup.2, for example, together with the carbon atoms to which they are attached, are a cyclohexane ring and R.sup.3 is ethylene, the side chains of the formula I being attached via ester linkages to tribasic or tetrabasic aromatic carboxylic acids present in the polyester main chain, the average molecular weight M.sub.w of the polyester being between 3,000 and 20,000 and the polyester having an acid number of 10 to 200. The polyesters are suitable, for example as a composition containing epoxide resins, for use as casting resins or in surface protection, particularly for the preparation of heat-resistant and weather-resistant powder paints.
