Nylons are widely used polyamides produced in large amounts from petrochemical-derived monomers. The production of fully biobased nylons using fermentatively produced diacids and diamines has been of great interest but not yet realized. Here, we report synthesis and characterization of bionylon-4,4 and -5,4, two rarely studied nylons, using succinic acid, 1,4-diaminobutane, and 1,5-diaminopentane produced by fermentation of metabolically engineered bacteria. The synthesized bionylons exhibit excellent thermotolerance and water absorptivity. To illustrate applicability, bionylons are also successfully used as a matting agent to reduce surface gloss of poly(acrylonitrile-co-styrene-co-acrylic) rubber. Furthermore, bionylon-4,4 and -5,4 are found to be biodegradable, providing further environmental benefit upon disposal. The strategy for the synthesis of fully biobased nylons comprising fermentative monomer precursor production and purification, polymerization, characterization, and application development reported here can serve as a guideline for synthesizing other fully biobased polymers from renewable resources.

完全生物基可生物降解尼龙-4,4和-5,4的合成，表征和应用

尼龙是由石油化学衍生的单体大量生产的广泛使用的聚酰胺。使用发酵生产的二酸和二胺生产全生物基尼龙已经引起了人们的极大兴趣，但尚未实现。在这里，我们报告了生物尼龙-4,4和-5,4的合成和表征，这两种很少研究的尼龙，使用的是琥珀酸，1,4-二氨基丁烷和1,5-二氨基戊烷，它们是由代谢工程菌发酵产生的。合成的生物尼龙表现出优异的耐热性和吸水性。为了说明其适用性，生物尼龙也成功地用作消光剂，以降低聚（丙烯腈-共-苯乙烯-共-丙烯酸）橡胶。此外，发现生物尼龙-4,4和-5,4是可生物降解的，处置后可进一步提高环境效益。本文报道的包括发酵单体前体生产，纯化，聚合，表征和应用开发在内的全生物基尼龙合成策略可作为从可再生资源合成其他全生物基聚合物的指南。
