Abstract  

Results on the preparation and thermoanalytical investigation of aliphatic bismaleamic acids and bismaleimides are presented. Correlations were established between the chemical structure and the thermal properties. The melting point and the thermal stability of the bismaleimides decrease as the number of carbon atoms in the structure increases. Chemically imidized samples have significantly higher thermal stability, which is almost independent of the chemical structure. Thermal polymerization begins just after the melting of the materials. A thermal fragmentation scheme is proposed, based on the results of mass spectrometry.
