Furfural, a compound easily manufactured from hemicellulose on the global scale, has gained attention as a second-generation biomass resource. The synthesis of oxabicyclodicarboxylic anhydride (OBCA) from furfural alone and its polymerization with diol to form the biobased and biodegradable polyoxabicyclate (POBC) make OBCA a novel biobased monomer building block. To control the physical properties of POBC, we synthesized a copolyester of butanediol (BD), succinic anhydride (SAh), and OBCA. The structures of the resultant poly(butylene succinate-co-butylene oxabicyclate) (P(BS-co-BO)) polymers were studied using ¹H and ¹³C NMR spectrometry, size-exclusion chromatography, thermal gravimetric analysis, differential scanning calorimetry, and wide-angle X-ray diffraction analysis. Physical properties of the melt-pressed films were examined by tensile strength testing, and the hydrolyzability of P(BS-co-BO)s was evaluated using a clear zone formation method with bacteria. To examine the environmental biodegradability of P(BS-co-BO), the biochemical oxygen demand for degrading their constituents was measured using the mixed inoculum method.

生物基聚丁二酸丁二酸酯-共-丁二烯氧杂双环酸酯的合成，物理性质和生物降解性

糠醛是一种易于在全球范围内由半纤维素制成的化合物，作为第二代生物质资源已受到关注。仅由糠醛合成草酸双环二羧酸酐（OBCA）并与二醇聚合形成可生物降解的可生物降解的多草双环酸酯（POBC），这使OBCA成为一种新型的基于生物的单体结构单元。为了控制POBC的物理性质，我们合成了丁二醇（BD），琥珀酸酐（SAh）和OBCA的共聚酯。用¹ H和¹³研究了所得的聚丁二酸丁二酸酯-共-丁烯基氧杂双环酸酯（P（BS-共-BO））聚合物的结构。13 C NMR光谱，尺寸排阻色谱，热重分析，差示扫描量热法和广角X射线衍射分析。通过拉伸强度测试检查了熔融压膜的物理性质，并使用透明区形成法与细菌一起评价了P（BS- co- BO）的水解性。为了检查P（BS- co- BO）的环境生物降解性，使用混合接种法测量了降解其成分的生化需氧量。
