Hydrogenated bisphenol-A polycarbonate (PHBPA) was successfully synthesized from dimethyl carbonate (DMC) and hydrogenated bisphenol-A (HBPA) by the method of two-step polycondensation. The chemical structure and the molecular weight of PHBPA was identified by ¹H-NMR spectra and gel permeation chromatography (GPC), respectively. In order to analyze the thermal degradation mechanism of PHBPA, a non-isothermal pyrolysis process was conducted and the violate products were detected using Fourier-transform infrared spectroscopy (FTIR) and gas chromatography–mass spectrometry (GC-MS). There were some reactions occurred during the pyrolysis including decarboxylation, disproportionation of the C–H transfer and β–H transfer, and the Fries rearrangement. In addition, the well-known Flynne–Walle–Ozawa (FWO) and Coats–Redfern kinetic analysis methods were used to calculate the values of activation energy and pre-exponential factors. Furthermore, isothermal pyrolysis experiments were performed and revealed that the reaction of decarboxylation occurred at 225 °C. This decarboxylation suggests that the molecular chain of PHBPA does not easily grow to a high-molecular-weight polymer.

采用两步缩聚法，由碳酸二甲酯（DMC）和氢化双酚A（HBPA）成功合成了氢化双酚A聚碳酸酯（PHBPA）。PHBPA的化学结构和分子量由¹鉴定H-NMR谱和凝胶渗透色谱法（GPC）分别。为了分析PHBPA的热降解机理，进行了非等温热解过程，并使用傅里叶变换红外光谱（FTIR）和气相色谱-质谱（GC-MS）检测了违规产物。热解过程中发生了一些反应，包括脱羧反应，CH转移和βH转移的歧化以及Fries重排。此外，使用著名的Flynne-Walle-Ozawa（FWO）和Coats-Redfern动力学分析方法来计算活化能和指数前因子。此外，进行了等温热解实验，结果表明脱羧反应发生在225°C。
