Procedure
204 g of allylbicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride are initially taken and 30 g of ethylenediamine are added dropwise, with stirring. The temperature rises to 130° C. The temperature is increased to 180° C.; in the course of this 14 ml of water distil off. Heating is then continued for a further 2 hours at 200° C. and under a pressure of 9.3 Pa. This gives 210 g of a yellow resin, solid at room temperature and having a softening point of 56° C., measured on a Kofler heated stage.
