摘要：

The thermosetting process of norbornene-ended polyimide. PMR II, was investigated by high resolution pyrolysis-gas chromatography-mass spectrometry (HR PyGC-MS) in a temperature range of 315-590 degreesC. The cross-linking reactions of PMR II under the temperature range of 330-390 degreesC for 0-20 h were discussed based on the composition and distribution of the pyrolyzates related to the end groups of the polymer. Then the thermosetting pathway and thermal decomposition mechanism of PMR-II polyimide were suggested. (C) 2002 Elsevier Science B.V. All rights reserved.
