Nowadays, research on biodegradable plastics has expanded to cover a wide variety of applicable fields. However, characteristics such as elastic properties are still difficult to achieve without using petroleum-based monomers. As environmental regulation forces the biomass-based monomer to be increased, polymers with 100% biomass-based monomers are being demanded. In this study, monomers derived from biomass such as adipic acid(AA), 2,5-furandicarboxylic acid(FDCA), and 1,3-propanediol(PDO) were used to synthesize terpolyester with the elastic property. Unsymmetric structure of FDCA leads to a spiral motif which can cause easier biodegradation, also it has ring structure so that it can sufficiently play a role as a hard domain of elastomer. Applying the “odd-even effect” which is used by 1,3-propanediol(PDO), causes much higher biodegradable rates, lower melting points, and a lower degree of crystallinity. |
