摘要

The gaseous products of high temperature pyrolysis (300℃ to 960℃) of aerylonitrile polymers were measured continuously under nitrogen atmosphere by on-line Fourier Transform Infrared Spectroscopic method (FTIR). From the variations of characteristic peaks it was found that the nitrogen of macromolecules evolved were mainly in the form of hydrogen cyanide and ammonia. During the pyrolysis amorphous carbonaceous element was formed

and crosslinked to form network structure. Three kinds of samples were used for comparison.The experimental results show that the gaseous products of volatile small molecules were HCN

NH3

CH4

C2H6 and cyanide.CO and CO2 were formed when copolymers of PAN were thermally pyrolyzed.
