| 摘 要： | 对共聚型阻隔聚酯PETNx(x为共聚酯中NDA占羧酸总质量的百分比)的热性能、流变性能和阻隔性能进行了研究。结果表明,PETNx体系属于假塑性流体。PETNx的CO2气体阻隔性优于常规PET;随着PETNx中NDA含量的增加,共聚物的玻璃化温度呈线性增高。

| Abstract: | The thermal property,rheological property and barrier property of the copolymer PETNx（x is the contents of NDA）was studied.The results indicate that PETNx is pseudoplastic fluid,the CO2 barrier property of PETNx was better than common PET.The glass transition temperature of the copolymer increased linearly with the increasing of NDA contents. |
