通过溶度参数等有关理论进行计算、分析及实验验证,找到了邻氯苯酚/氯仿(1/3,ml/ml)可作为聚对苯二甲酸丁二醇酯(PBT)的溶剂和室温淋洗剂。用自行制备的一系列分子量不同的PBT样品标定柱,建立了用凝胶色谱在室温下测定PBT分子量和分子量分布的方法,并得到了PBT和PS在邻氯苯酚/氯仿(1/3,ml/ml)体系中,25.0℃的[η]-M方程。发现在此GPC体系中普适标定法可以适用。 Through the calculation and analysis of the solubility parameters and other related theories, we found that o-chlorophenol / chloroform (1/3, ml / ml) can be used as the solvent of PBT and room temperature lotion. A series of PBT sample calibration columns with different molecular weight were prepared and the method of determining the molecular weight and molecular weight distribution of PBT by gel chromatography was established. The results showed that the PBT and PS were separated in o-chlorophenol / chloroform (1/3, / ml) system, the [η] -M equation at 25.0 ° C. The universal calibration method was found to be suitable for use in this GPC system.
