摘　　要：以癸二酸和间苯二甲胺为原料,通过高温高压熔融聚合的方法,初步探索尼龙MXD10的合成工艺。在此基础上,对合成的半芳香族尼龙MXD10进行性能表征。通过傅里叶红外光谱仪对尼龙MXD10的结构进行分析;通过差示扫描量热仪、热重分析仪对尼龙MXD10的热性能进行分析。结果表明:尼龙MXD10的熔融温度为175℃,结晶温度为117℃;热分解为一步分解法。对尼龙MXD10进行非等温结晶动力学分析,通过Jeziorny方程、莫志深法对半芳香族尼龙MXD10非等温结晶动力学进行综合研究。结果表明:半芳香族尼龙MXD10的晶体生长为二维生长,结晶温度随降温速率的提高而降低,活化能为-981.625 kJ/mol。The article used sebacic acid and meta phenylenediamine as raw materials,and explored the synthesis process of nylon MXD10 through high-temperature and high-pressure melt polymerization.On this basis,the performance of the synthesized semi-aromatic nylon MXD10 was characterized.The structure of nylon MXD10 was analyzed using Fourier transform infrared spectroscopy.The thermal properties of nylon MXD10 were analyzed by differential scanning calorimetry and thermogravimetric analyzer.The results showed that the melting temperature and crystallization temperature of the synthesized nylon MXD10 were 175°C and 117°C,respectively.Thermal decomposition was a one-step decomposition method.Non isothermal crystallization kinetics analysis was also conducted on nylon MXD10,and the non isothermal crystallization kinetics of semi-aromatic nylon MXD10 were studied comprehensively through the Jeziorny equation and Mo Zhishen method.The results indicate that the crystal growth of semi-aromatic nylon MXD10 is two-dimensional,and the crystallization temperature decreases with the increase of cooling rate.The activation energy is-981.625 kJ/mol。
