ABSTRACT Herein, we report a novel transparent engineering plastic nylon 10I/10T based on bio-based poly(decamethylene isophthalamide) (nylon10I). We have demonstrated the one-step melt polycondensation synthesis of transparent nylon and carried out Fourier transform infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance (1H NMR) to confirm the chemical structure. Furthermore, the dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) were used to analyze the thermal properties. Glass transition temperature (Tg) and thermal decomposition onset temperature (T1) of nylon 10I/10T (15 wt. % 10T) were 118.9 and 438.0 °C, respectively. The intrinsic viscosity, water absorption, light transmittance, mechanical properties, solvent resistance and the decomposition mechanism of nylon 10I/10T have also been investigated. The results show that the nylon 10I/10T has lower water absorption and enhanced solvent resistance compared to nylon 6–3-T, which indicates that nylon 10I/10T is a promising transparent plastic.

生物基透明尼龙10I/10T的合成、表征和热分解动力学

摘要在此，我们报告了一种基于生物基聚（十亚甲基间苯二甲酰胺）（nylon10I）的新型透明工程塑料尼龙 10I/10T。我们已经展示了透明尼龙的一步熔融缩聚合成，并进行了傅里叶变换红外光谱 (FT-IR) 和质子核磁共振 (1H NMR) 以确认化学结构。此外，动态力学分析（DMA）和热重分析（TGA）用于分析热性能。尼龙 10I/10T（15 重量% 10T）的玻璃化转变温度 (Tg) 和热分解开始温度 (T1) 分别为 118.9 和 438.0 °C。还研究了尼龙10I/10T的特性粘度、吸水率、透光率、力学性能、耐溶剂性和分解机理。
