The Properties of Poly(ester amide)s Based on Dimethyl 2,5-Furanedicarboxylate as a Function of Methylene Sequence Length in Polymer Backbone

Abstract: A series of poly(ester amide)s based on dimethyl furan 2,5-dicarboxylate (DMFDC), 1,3-propanediol (PDO), 1,6-hexylene glycol (HDO), and 1,3-diaminopropane (DAP) were synthesized via two-step melt polycondensation. The phase transition temperatures and structure of the polymers were studied by differential scanning calorimetry (DSC). The positron annihilation lifetime spectroscopy (PALS) measurement was carried out to investigate the free volume. In addition, the mechanical properties of two series of poly(este… Show more

“…The glass transition temperature (T g ) of the resulting material is 55.9−73.9 °C. 218,220 In addition, TPA-based polyesters exhibited a higher maximum T g and melting temperature (T m ) than 2,5-FDCAbased polyesters. Besides, the T g and T m of the polyesters and copolyesters improved step by step with decreasing diol length, which almost fitted as a straight line.…”

“…In addition to an improvement in the PPAF molar fraction, a significant improvement in the glass transition temperature has been observed owing to the rigid action of the molecular hydrogen bond of the amide group. The glass transition temperature ( T g ) of the resulting material is 55.9–73.9 °C. , In addition, TPA-based polyesters exhibited a higher maximum T g and melting temperature ( T m ) than 2,5-FDCA-based polyesters. Besides, the T g and T m of the polyesters and copolyesters improved step by step with decreasing diol length, which almost fitted as a straight line.…”
