Synthesis of high molecular weight furan based copolyester and its thermal, mechanical properties |
초록 |
Furan-2,5-dicarboxylic acid (FDCA) is considerable attention as substituent that can replace terephthalic acid as a biomass derived monomer. By the two step polymerization, we have synthesized a high molecular weight furan based copolyester, poly(butylene adipate-co-furanoate) (PBAF). Depending on the feed ratio of acid monomers, adipic acid and dimethyl furan-2,5-dicarboxylate, block composition could be controlled. Amongst PBAF series, PBAF90 showed highest tensile strength (σ) of 83.4 MPa and elongation at break (ε) of 501 %. Synthesized FDCA based polyester surpasses the mechanical properties of conventional PBAT. These results were induced by the effective micro-separation between hard and soft domains owing to the rigidity of the furan ring and flexibility of butylene adipate block that leads to elastomeric behavior. |
