摘　　要：以2,5-呋喃二甲酰氯(FDCl)和脂肪族二胺(C=4、6、8)为原料,通过界面聚合法合成了一系列生物基呋喃PA(PAXFs),包括聚四亚甲基呋喃酰胺(PA4F)、聚六亚甲基呋喃酰胺(PA6F)和聚八亚甲基呋喃酰胺(PA8F)。傅里叶变换红外光谱仪(FTIR)、核磁共振光谱仪(NMR)以及凝胶渗透色谱仪(GPC)结果表明,成功制备了高分子量的PAXFs。差示扫描量热仪(DSC)和X-射线衍射仪(XRD)结果表明,PA4F是半结晶PA,而PA6F和PA8F是无定形PA,这可能是由于分子链中呋喃环间的相互作用以及呋喃环和丁二胺结构单元的共平面特性,导致PA4F的分子链较规整,结晶程度高。热失重分析仪(TG)和紫外-可见光分光光度计(UV-vis)结果表明,PAXFs具有良好的耐热性和透明性,最大热分解温度和紫外可见光760 nm处的透过率分别高达450℃和91.1%。A series of furan-based polyamides(PAXFs),including poly(tetramethylene furanamide)(PA4F),poly(hexamethylene furanamide)(PA6F),and poly(octamethylene furanamide)(PA8F),were synthesized using 2,5-fu-randiformyl chloride and aliphatic diamines(C=4,6,8)as raw materials through interfacial polymerization.The charac-terization results obtained from FTIR,NMR and GPC tests confirmed the successful preparation of PAXFs with a high molecular weight.DSC and XRD analysis results indicated that PA4F was a semi-crystalline polyamide,whereas PA6F and PA8F were amorphous polyamides.This result may be due to the interaction between the furan ring and furan ring in the molecular chain as well as the coplanar structure of the furan ring and butylamine units,which resulted in a more regu-lar molecular chain and a higher crystallinity degree of PA4F.TGA and UV-vis spectroscopy characterization results in-dicated that PAXFs had good heat resistance and transparency,and its maximum thermal decomposition temperature and transmittance at 760 nm of UV visible light reached 450℃and 91.1%,respectively.
