In this study, the sugar-based monomer isosorbide (IS) was used to improve the properties of poly(butylene succinate) (PBS). The molecular weight of all copolyesters was approximately 100 000 g/mol, and they presented a random microstructure combined with excellent thermal stability. The IS-containing copolyesters were all semicrystalline, and both their crystallinity and crystallization rate decreased with the introduction of the rigid structure of IS into the PBS chain. IS also had an effect on the mechanical properties and gas barrier properties of the copolyesters. Blown films from poly(butylene-co-isosorbide succinate) copolyesters were prepared. The gas barrier and mechanical properties achieved a significant improvement after blowing.

吹膜挤出后聚丁二酸丁二醇酯共聚物的性能

在这项研究中，糖基单体异山梨醇（IS）用于改善聚丁二酸丁二酯（PBS）的性能。所有共聚酯的分子量约为100 000 g / mol，它们呈现出无规的微观结构和出色的热稳定性。含IS的共聚酯都是半结晶的，并且随着IS的刚性结构引入PBS链，它们的结晶度和结晶速率均降低。IS对共聚酯的机械性能和阻气性能也有影响。由聚（丁烯-共-异山梨醇琥珀酸酯）共聚酯制备吹塑薄膜。吹塑后的阻气性和机械性能得到了显着改善。
