摘要：
The thermal performance and the decomposition mechanism of the cyclotriphosphazene based homopolymer were investigated by means of TGA, DTG and integrated TG/FTIR analysis. The thermal decomposition of the homopolymer between 100 and 800 degrees C includes two stages; the initial degradation temperature of the first stage is about 377 degrees C with the 292 kJ/mol of average decomposition activation energy. Accordingly, the possible thermal decomposition mechanism of the homopolymer was proposed. In addition, the LOI (34.3 %) calculated from the amount of char remaining indicates the homopolymer is self-extinguishing in air.
