X-ray photoelectron spectroscopy analysis shows that polyimide is thermally converted to glassy carbon during pyrolysis. Scanning tunneling microscopy gives direct evidence of the existence of small graphitic domains in the amorphous carbon matrix, and we believe that those surface graphitic structu
## Abstract Thermal properties of a new semicrystalline polyimide synthesized from 3,3β²,4,4β²βbenzophenonetetracarboxylic dianhydride (BTDA) and 2,2βdimethylβ1,3β(4βaminophenoxy)propane (DMDA) have been studied. Heat capacities in the solid and liquid states of BTDAβDMDA have been measured. The heat
