摘 要：Fully biomass-based poly(butylene succinate) (PBS) was obtained by polycondensation of biomass-based 1,4-butanediol and biomass-based succinic acid or dimethyl succinate. Succinic anhydride (SAn) and tetrahydrofuran (THF) were also synthesized from furfural. Fully biomass-based poly(butylene oxide-co-butylene succinate) was obtained by ring-opening polymerization of biomass-based SAn and THF. Partially biomass-based poly(butylene terephthalate) was obtained by polycondensation of biomass-based 1,4-butanediol and petroleum-based terephthalic acid. The biomass carbon ratio calculated from ~(14)C concentrations measured by accelerator mass spectroscopy verified that the PBS obtained in this study contained only biomass carbon.
