【摘要】 <正> 用反相色谱法测定了含氯量在40.5—51.2％的四个氯化聚乙烯试样于不同温度（50—120℃）下,对苯、甲苯、四氢呋喃的比保留值Vg°,由Vg°得到试样与溶剂分子的相互作用参数X₁和X₁随温度的变化情况。 实验所得X₁—T的曲线均为凹形曲线,更多还原

【Abstract】 The special retention volumes of several solvents, such as bezene, tetrahydrofuraa and toluene, on the chlorinated polyethylenes containing different amounts of chloride are determined by inverse gas chromatography at Various tempera-tures(50-120℃) The interaction parameter between the sample and the solvent is obtained from the special retention volume Vg0. And it is found that the parameter X1 varies with the temperature.The x1-T curves obtained experimently are all upward concave. It gives a minimum value. The temperature corresponding to this value increases with the chlorine in the chlorinated polyethylene.Beijing Keseasch Institute of Chemical Industry更多还原
