ABSTRACT:
Polyimides are obtainable by reacting a dianhydride component with a diamine component, at least one diamine containing cycloaliphatic units, with the proviso that the dianhydride component is a mixture of different dianhydrides if the diamine component consists only of one diamine containing cycloaliphatic units and the diamine component is a mixture of different diamines if the dianhydride component consists of only one dianhydride.
