The super-tough bio-based nylon was prepared by melt extrusion. In order to improve the compatibility between bio-based nylon and elastomer, the elastomer POE was grafted with maleic anhydride. Scanning Electron Microscopy (SEM) and Thermogravimetric Analysis (TGA) were used to study the compatibility and micro-distribution between super-tough bio-based nylon and toughened elastomers. The results of mechanical strength experiments show that the 20% content of POE-g-MAH has the best toughening effect. After toughening, the toughness of the super-tough nylon was significantly improved. The notched impact strength was 88 kJ/m² increasing by 1700%, which was in line with the industrial super-tough nylon. X-ray Diffraction (XRD) and Differential Scanning Calorimetry (DSC) were used to study the crystallization behavior of bio-based PA56, and the effect of bio-based PA56 with high crystallinity on mechanical properties was analyzed from the microstructure.

超韧生物基尼龙是通过熔融挤出制备的。为了提高生物基尼龙与弹性体之间的相容性，将弹性体POE与马来酸酐接枝。使用扫描电子显微镜（SEM）和热重分析（TGA）来研究超韧生物基尼龙和增韧弹性体之间的相容性和微观分布。机械强度实验的结果表明，POE-g-MAH的20％含量具有最佳的增韧效果。增韧后，超韧尼龙的韧性显着提高。缺口冲击强度为88 kJ / m ²增长了1700％，与工业超韧尼龙相吻合。利用X射线衍射（XRD）和差示扫描量热法（DSC）研究了生物基PA56的结晶行为，并从微观结构分析了高结晶度的生物基PA56对力学性能的影响。
