| 要約: | In this research, a furan-based liquid crystal polymer (FLCP) was synthesized through a one-pot chemical reaction. The effects of incorporating 2,5-furandicarboxylic acid (FDCA) into the polymer were characterized using a range of analytical techniques. The results demonstrated that the incorporation of FDCA effectively reduced the polymer’s water absorption rate. When FDCA was substituted for PTA up to a ratio of 50%, the thermal decomposition temperature of the polyester was found to be relatively stable with only a minor reduction. Moreover, the addition of FDCA led to an increase in the polyester’s viscosity and enhanced melt strength, which imply that the copolyesters have stronger deformation processing ability under the external force. This copolyester demonstrates favorable thermal stability, melt processing characteristics, mechanical performance, and hydrophobic behavior, suggesting substantial promise in medical and packaging applications.
