Exploration of Structure–Property Relationships by Altering Glycol Backbone Unsaturation (Double/Triple Bonds) in Furan‐Based Polyesters

This study highlights both the challenges and opportunities associated with developing bio‐based furanic polyesters. Incorporating unsaturated moieties into glycol chains effectively modulates polymer rigidity and thermal properties, though it requires careful optimization of polymerization conditions. The findings demonstrate the viability of solution polycondensation for synthesizing high‐quality FDCA‐based polyesters with unsaturated glycols and pave the way for further investigations into polymer design strategies that balance flexibility, thermal stability, and environmental sustainability.
