摘要
用反相色谱法研究了聚环氧乙烷、聚环氧丙烷和聚四氢呋喃的溶解度参数，按Ｇｕｉｌｌｅｔ的方法得到１２０℃时的溶解度参数分别为８．９３、８．２７和８．２１（ｃａｌ／ｃｍ３）．本文讨论了方法的准确性和合理性，并用二元溶解度参数公式代替Ｈｉｌｄｅｂｒａｎｄ公式对实验结果进行处理，得到了聚醚溶解度参数的非极性部分，它们分别为６．４４、７．１５和７．５３（ｃａｌ／ｃｍ３）．
The solubility parameters of PEO (polyethylene oxide), PPO(polyepoxypropane) and PTHF (polytetrahydrofuran) have been studied by inverse gas chromatography using Guillet's method. The parameters at 120℃ are obtained as 8. 93, 8. 27& 8. 21 (cal/cm3)1/2respectively. The reasonability and precision of inverse gas chromatography are discussed. Instead of Hildebrand equation to treat the results of experiment,the equation of two-dimensional solubility parameters has been used to gain the nonpolar part of solubility parameters of polyether. They are 6. 44,7. 15,and 7. 53 (cal/cm3)1/2respectively.
