摘要：Benzocyclobutene-terminated imides were prepared and fully characterized with H-1 NMR, MS, and FT-IR. The thermal degradation of polymers was investigated by using thermogravimetric analyzer (TGA) and high-resolution pyrolysis-gas chromatography-mass spectrometry (HR-Py-GC-MS). TGA showed that thermal degradation of the polymer was a single-stage process in N-2, whereas a three-stage degradation in air atmosphere. The major involved products were found to be CO2, naphthalene and naphthalene derivatives. Degradation mechanism of the polymer was suggested and the relationship between structures of the polymer and degradation products was also discussed. (c) 2004 Elsevier B.V. All rights reserved.
