Bio-based polyamide as well as preparation method and application thereof

The invention relates to the technical field of bio-based polymers, and provides bio-based polyamide as well as a preparation method and application thereof. According to the bio-based polyamide, adipic acid in polyamide 6/66 is partially replaced by 2, 5-furandicarboxylic acid, and the prepared bio-based polyamide is not only good in environmental protection property, but also better in mechanical strength and heat resistance, and can be applied to the fields of engineering plastics, fibers and the like. 本发明涉及生物基聚合物技术领域，提供了一种生物基聚酰胺及其制备方法及应用。所述生物基聚酰胺采用2,5-呋喃二甲酸部分替代聚酰胺6/66中的己二酸，制备得到的生物基聚酰胺不仅环保性好，并且具有更好的力学强度和耐热性能，可应用于工程塑料、纤维等领域。
