【摘要】 用GPC测定了五种不同单体比的共聚醚与硝酸酯的相溶性。测定结果显示: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。更多还原

【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.更多还原
