Mechanism investigation of thermal degradation of CO2-based poly(cyclohexene carbonate caprolactone)

Publication date: Available online 4 September 2019Source: Polymer Degradation and StabilityAuthor(s): Yonghang Xu, Tao Zhang, Yiluan Zhou, Danmin Zhou, Zixin Shen, Limiao LinAbstractThe thermal degradation behaviors and mechanisms of CO2-based poly(cyclohexene carbonate caprolactone)s (PCHCCLs) were deeply studied taking advantage of thermogravimetric analysis/Fourier transform infrared spectrometry (TG/FTIR) and pyrolysis gas chromatography/mass spectrometry (Py-GC/MS) techniques. The experimental results indicate that the decomposition temperatures of PCHCCLs increase with the increasing contents of polycaprolactone (PCL) segments. Backbiting reaction was found to be the dominant degradation pathway for PCHCCLs, and a complicated random rupture process was also observed at higher pyrolysis temperature.
