摘要
在PET的聚合过程中,添加二甲基T4T制备大分子链上含有酰胺基团的改性聚酯(PET-PA4T)。利用1H-NMR,元素分析检测了所合成的聚合物。应用DSC、等温结晶动力学和光学解偏振研究了PET-PA4T的结晶特性。
During the polymerization of poly(ethyleneterephthalate), N,N ′bis(pcarbomethoxybenzoyl)butanediamine (T4TDimethyl) was employed, the modified poly(ethyleneterephthalate) (PETPA4T) contained amide linkage in the macromolecular chains was obtained. 1HNMR and elemental analysis were used to measure the composition of PETPA4T. The crystalline characterization of PETPA4T was investigated by means of DSC, isothermal crystalline dynamics and polarized light intensity determination.
