Anhydroxylitol tripelargonate (AXP), a novel environmentally sustainable plasticizer for poly(lactic acid)/poly(butylene succinate) (PLA/PBS) blends, is successfully synthesized. The chemical structure of AXP is confirmed by FTIR and 1H-NMR. The influence of varying the addition of AXP on mechanical property, thermal property, crystallization, rheological behavior and micromorphology of PLA/PBS blends is investigated in detail. The results are shown that the toughness and elongation at break of the blends are improved gradually with the increase of plasticizer addition, which indicates that plasticizer play a good plasticizing role in toughening blends. Furthermore, the introduction of AXP reduces the glass transition temperature (Tg) of the blends and simultaneously enhances its crystallization and processability. Observing the impact section of blends by SEM, it can be found that plasticizer AXP could change the blend from brittle fracture to ductile fracture. Additionally, the plasticization of AXP rivalled those petro-based plasticizers, and could be potential substitute to supplant O-benzene plasticizer in the future industry.

新型环保可持续木糖醇增塑剂:合成与应用

Anhydroxylitol tripelargonate (AXP) 是一种用于聚乳酸/聚丁二酸丁二醇酯 (PLA/PBS) 共混物的新型环保增塑剂,已成功合成。AXP 的化学结构由 FTIR 和1核磁共振。详细研究了不同 AXP 添加量对 PLA/PBS 共混物的机械性能、热性能、结晶、流变行为和微观形貌的影响。结果表明,随着增塑剂添加量的增加,共混物的韧性和断裂伸长率逐渐提高,表明增塑剂对共混物增韧起到了很好的增塑作用。此外,AXP 的引入降低了共混物的玻璃化转变温度 (Tg),同时提高了其结晶度和可加工性。通过扫描电镜观察共混物的冲击截面,可以发现增塑剂AXP可以使共混物从脆性断裂转变为韧性断裂。此外,AXP 的增塑作用可与石油基增塑剂相媲美,
