中文摘要	poly(ethylene 2, 5-furandicarboxylate) (pef) was synthesized via direct esterification method based on 2, 5-furanicarboxylica acid and ethylene glycol. stannous oxalate was used as catalyst. the results showed that the direct esterification method was a straightforward and convenient effective way for preparing pef. the results of fourier transform infrared spectroscopy (ftir) and nuclear magnetic resonance spectroscopy (h-1-nmr) confirmed the expected pef structure. the results of ubbelohde viscosity method and gel permeation chromatography (gpc) declared the relationship between intrinsic viscosities and weight-average molecular weight was [eta] = 2.82 x 10(-6) m-w (0.99) [dl/g, 25 degrees c, phenol-tetrachloroethane (1: 1, w/w)]; the results of differential scanning calorimeter (dsc) displayed that the glass transition (t-g) of pef was 84 degrees c which was 16 k higher than that of poly(ethylene terephthalate) (pet) and the melting temperature (t-m) of pef was 211 degrees c which was 43 k lower than that of pet. the results of thermogravimetric analysis (tga) showed that the pef was thermally stable up to 373 degrees c pef had good thermal properties and was similar to that of pet. the results of coaxial cylinder viscometer showed that the pef melt was a pseudoplastic newtonian fluid and its non-newtonian index increased with decreasing of relative molecular weight and increasing of temperature. non-newtonian index was about 0.85 (melting temperature = 230 similar to 250 degrees c, rate of shear = 2.17 x 10(-2) similar to 1.14 x 10(2) s(-1)).
