| 摘 要： | 用GPC测定了5种不同单体比的共聚醚与硝酸酯的相溶性.测定结果表明:随共聚醚主链中环氧乙烷单元的增多,硝酸酯的相溶性增加.测定的相对标准偏差<3％.这表明,用GPC测定共聚醚与硝酸酯的相溶性是一种迅速、准确、可靠的方法。

| Abstract: | The miscibility limits of five different monomer ratio CO-polyethers P(E-CO-T)] with nitrates (NG, BTTN and NG+BTTN) were measured by GPC (Gel Permeation Chromatography). Results revealed that as the number of ethylene oxide units in the mainchains of CO -polyether increases, the miscibility limits will also increase. The relative standard deviation of the measurements was less than 3%. The results show that GPC is a fast, accurate and reliable method for determining the above miscibility. |
