摘　　要：以2,5-呋喃二甲酸二甲酯(DMFDCA)和三甲基六亚甲基二胺(TMD)为原料,通过熔融聚合制备了含呋喃环的生物基聚酰胺-聚呋喃二甲酰三甲基六亚甲基二胺(PAFTMD),分别采用红外光谱和核磁共振波谱证实了PAFTMD具有聚酰胺的结构特征。差示扫描量热仪和X射线衍射仪的测试结果表明,PAFTMD呈现一种非晶态的无定形结构,这主要是由于,呋喃环对分子间氢键的抑制作用和三甲基六亚甲基二胺的非对称结构破坏了PAFTMD分子链的规整度。同时非晶态的特性赋予了PAFTMD在380~780 nm范围内具有较高的透光率,其值为92%。此外,还研究了PAFTMD在不同有机溶剂中的溶解性。Biobased furan-containing polyamides poly(trimethyl hexamethylene furanamide)(PAFTMD)were synthesized from dimethyl furan-2,5-dicarboxylate and trimethylhexamethylene diamine by melt polymerization.Fourier transform infraredspectroscopy(FTIR)and nuclear magnetic resonance spectroscopy(NMR)were used to identify the structure of PAFTMD.The results of differential scanning calorimeter(DSC)and X-ray diffractometer(XRD)showed that PAFTMD was an amorphous polymer due to the inhibitory effect of furan ring on the intermolecular hydrogen bond and the demage of asymmetric structure of trimethylhexamethylene diamine on the regularity of molecular chains,which contributed to the high transmittance(92%)of PAFTMD films in the range of 380~780 nm.In addition,the solubility of PAFTMD in several organic solvents was also studied.
