1.Water soluble alkyd resin was synthesized from oleic acid as fatty acid,maleopimaric acid imide,dimaleopimaric acid imide,glycerol as raw materials. Effects of oleic acid dosage,ratio of polyols acid,kinds of polyacid on properties of product were discussed.
以油为脂肪 ,马来海松酰亚胺、双马来海松酰亚胺及甘油为原料 ,合成改性松香类水溶性醇树脂 ,讨论了油用量、醇配比、多元的种类对产物性能的影响。收藏指正
2.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。收藏指正
3.Moreover, FTIR,DSC and TGA were used to characterize PAA and PI. It was found that the glass transition temperature(?T??g) and thermal stability of PI decreased with the increase of flexibility of dianhydrides and there were the characteristic bands of amic acid and imide in the infrared spectra of PAA and PI,respectively.
此外还利用红外光谱(FTIR)、差分扫描量热法(DSC)、热重分析(TGA)等对聚酰亚胺进行了表征,结果表明聚酰亚胺(PI)的玻璃化温度(tg)和热分解温度(td)随着聚合单元长度的增加而降低。收藏指正
