【摘要】 High molecular weight poly（1,4-butylene 2,5-furandicarboxylate-co-isosorbide 2,5-furandicarboxylate） copolyesters （PBSIF-x） were synthesized via melt-polycondensation of 2,5-furandicarboxylic acid （FDCA）,with varying ratios of isosorbide （ISB） and 1,4-butylene glycol （BDO） catalyzed by antimony trioxide （Sb₂O₃）.The PBSIF-x structures were investigated using FTIR and ¹H NMR,while the GPC analysis exhibited the copolyesters molecular weights with number average molecular mass （M_n） in the range of 11 079-15 153 g/mol.The DSC results show that PBSIF-x copolyesters have a single glass-transition temperature （T_g）（77.45-110.96 ℃）,increasing with the increase in ISB content,while TGA analysis demonstrates excellent thermal stability up to 320 ℃.From the thermal result,properties of PBSIF-x copolyesters are found to be within the interval of their parent homologues poly（butylene 2,5-furandicarboxylate）（PBF） and poly（isosorbide 2,5-furandicarboxylate）（PIF）,which confirms the aromatic/aliphatic blending within the polymer matrix for enhanced polymer stability and performance.更多还原
