酰胺基改性聚酯的合成及性能测试

Synthesis and performance testing of amide modified polyester

首先合成了含有酰胺键的组分T4T、T2T ,然后按一定物质的量比将T4T、T2T分别与EG反应制备含有酰胺键的改性聚酯。通过DSC密度法等测定改性聚酯的超分子结构 ,并测试了改性聚酯的吸湿率。结果发现 ,随着T4T含量的增加 ,聚酯的吸湿率明显增大。

The component with amido bond such as T4T and T2T are synthesized at first,then it is polymerized with EG in a given of amount of substance ratio to prepare amide modified polyester.The super molecular structures are tested by DSC density method and also the moisture pickup are measured.It is found out that the wet pickup will increase with the increasing of the content of T4T in the modified polyester .
