摘要

<正> Three kinds of polypyrrolones （PMDA-DAB

PMDA-TADPE and DEDA-DAB） werepyrolyzed at high temperature in order to study the effect of the chain structure of polypyrro-lones on the electrical properties of the pyrolyzed polymers. Results show that the num-ber of fusing rings in the main chain of polymers has a little effect on the pyrolysis pro-cess

whereas

the ether bond in the main chain plays an important role during pyrolysis.Structure characterizations by elemental analyis

XPS spectra

X-ray diffraction and SEMimages indicate that because the ether bond is easy to break

it is difficult to form largearea planar network. This hampers the formation of the graphite-like structure in thepolypyrrolones containing ether bond even after being pyrolyzed at 1200℃.
