摘　　要：The thermal decmpos ition of polyani line(PAn) and poly-o-toluidine (POT)was studied by means of direct pyrolysis mass spectrometry (DPMS) and MS/MS. The results showed that both benzene-diamine and guinone-diimine units were produced,and the intensities of fragments corresponding to quinone-diimine units increased as the oxidation degrees increased The mechanism of thermal decomposition of PAn and POT was given for the first time.The thermal decmpos ition of polyani line(PAn) and poly-o-toluidine (POT)was studied by means of direct pyrolysis mass spectrometry (DPMS) and MS/MS.
