ABSTRACT Poly(ethylene 2,5‐furandicarboxylate) (PEF) and poly(butylene (PBF) are regarded as two of the most promising materials derived from furandicarboxylic acid. The modification these polyesters has become one hot research topics. It was reported that their mechanical properties had significant shortcomings, particularly for low molecular weight PBF, whose brittleness limited its use. In this work, a novel monomer, itaconic acid, introduced to modify new furan‐based polyester‐poly(1,4‐butylene furanoate‐co‐itaconate) (PBFIs) synthesized. For first time, acid up 47% incorporated synthesize polyester materials. structural thermomechanical were investigated using Gel Permeation Chromatography (GPC), Proton Nuclear Magnetic Resonance ( 1 H NMR), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), X‐ray Diffraction (XRD), tensile testing. Compared PBFIs exhibited reduced crystallization ability attributed formation crosslinked networks; notably, glass transition temperature decreased significantly 7°C, while thermal stability improved. Tensile tests further demonstrated elongation at break increased dramatically by 675%. summary, results suggest possess potential in realm thermoset elastomers, thereby expanding application scope polyesters.
