While modern research into biodegradable and renewable plastics has expanded to cover a wide variety of applications, some characteristics, such as desirable elastic properties, are still difficult to achieve without the use of petroleum-based monomers. In addition, 100% biomass-based polymers are in high demand as environmental regulations increasingly require the use of biomass-based monomers. This study used biomass-derived monomers, 2,5-furan dicarboxylic acid (FDCA), and 1,3-propanediol (PDO). The unsymmetrical structure of FDCA led to a spiral motif that biodegrades efficiently, and its ring structure also plays an important role as a hard elastomer domain. Applying the “odd–even effect” of PDO resulted in very high biodegradadation rates, low melting points, and low degrees of crystallinity. An FDCA:AA ratio of 7:3 led to an elongation of around 600% and a recovery rate of 89% (to the original state) at a fixed PDO concentration.
