Advances in hyperbranched polymer with terminal amido .

端氨基超支化聚合物的研究进展。

Ir is often used to investigate the reaction of thermal imine because the groups of amido acid and imide possess characteristic ir spectroscopy and ir method has the merits of simpleness , convenience and speediness .

由于红外光谱法具有简单、方便、快速等特点，酰胺酸、酰亚胺基团又有着特定的红外吸收峰，因而成为研究热亚胺化反应最常用的测试方法。
