超支化聚酯的合成及在不同酸度下的聚集形态

Applies of Hyperbranched Polymers and Synthesis and Gathered Forms Under Different Acidity of Hyperbranched Polyesters

以苯 - 1,2 ,4 -三羧酸 - 1,2 -酐 (BTAA)和二乙醇醚为原料合成超支化聚酯 .在超支化聚酯的末端用 4 -氨基 - 1,8-萘酰亚胺 (NPI)作荧光标记 ,得知在可见光区有强荧光的超支化荧光聚酯 .酸度对NPI及荧光超支化聚合物有不同影响 .

The hyperbranched polyester was synthesized by benzene-1,2,4-tricarboxylic-1,2-anhydride and dihydroxy ethers. And hyperbranched polyester was marked by fluorescence at the terminal by 4-Aminon 1,8-Naphthalimide, by which the authors researched the change of the fluorescence character in action under the different acidity and findlly the different gathered forms of hyperbranched polyesters.
