A series of phosphorus-containing poly (hexamethylene 2,5-furandicarboxylate)s (PHFCs) were synthesized from available biobased 2,5-furandicarboxylic acid (FDCA), 1,6-hexanediol (HDO), and 2-carboxyethyl (phenyl)phosphinic acid (CEPPA). Microstructure, molecular weight and its distribution, crystallization behavior, thermal, mechanical and flame retardant properties were characterized. Moreover, the effects of composition on various properties were investigated systematically. All PHFCs exhibited the excellent thermal stability. Glass transition temperature of PHFC slightly decreased with the increasing of CEPPA. Furthermore, nano-TiO₂ not only improved the molten drops phenomenon, but also increased the crystallization rate. The limiting oxygen index of PHFC with 10 mol% CEPPA and 1 wt% TiO₂ was 26% and UL94V-0 rating was obtained.

从可用的生物基2,5-呋喃二甲酸（FDCA），1,6-己二醇（HDO）和2-羧乙基（苯基）合成一系列含磷的聚（6,5-呋喃二甲酸六亚甲基酯）（PHFC）次膦酸（CEPPA）。表征了微结构，分子量及其分布，结晶行为，热，机械和阻燃性能。此外，系统地研究了组成对各种性能的影响。所有PHFC都表现出出色的热稳定性。随着CEPPA的增加，PHFC的玻璃化转变温度略有下降。此外，纳米TiO ₂不仅改善了熔滴现象，而且提高了结晶速率。具有10 mol％CEPPA和1 wt％TiO ₂的PHFC的极限氧指数 为26％，并获得UL94V-0等级。
