abstract	The search for new polymers from renewable origin is a sparkling field in polymer chemistry, especially those having promising properties, for example, in terms of their thermal performance. In this vein, in this study, an original renewable 2,5-furandicarboxylic acid-based cycloaliphatic homopolyester, poly(1,4-cyclohexylene 2,5-furandicarboxylate) (PCdF), is synthesized from dimethyl-2,5-furandicarboxylate and 1,4-cyclohexanediol. Poly(1,4-cyclohexanedimethylene 2,5-furandicarboxylate) is also prepared for comparison purposes, since it is the direct renewable substitute of poly(1,4-cyclohexanedimethylene terephthalate) and they are structurally related. The resulting homopolyesters are characterized in detail by using attenuated total reflectance Fourier transform infrared, H-1, C-13 and 2D NMR, X-ray and elemental analysis, and thermal properties are assessed by thermogravimetric analysis, differential scanning calorimetry, and dynamic mechanical thermal analysis. PCdF shows to have a semicrystalline character, exhibiting an extremely high glass transition temperature around 175 degrees C. Moreover, this polyester also shows to be a high thermally stable material with a degradation temperature of 380.0 degrees C.
