标准摘要
[中文适用范围]: 本文件规定了在 60 °C 至 220 °C 温度下使用有机洗脱液通过尺寸排阻色谱 (SEC) 测定聚合物的平均分子量和分子量分布的方法(参见附录 A)。 平均分子量和分子量分布由使用聚合物标准品制作的校准曲线计算。 因此,该测试方法被归类为相对方法(参见ISO 16014-1)。 [外文原描述]: This document specifies a method for determining the average molecular weight and the molecular weight distribution of polymers by size-exclusion chromatography (SEC) using an organic eluent at temperatures between 60 °C and 220 °C (see Annex A). The average molecular weight and the molecular weight distribution are calculated from a calibration curve prepared using polymer standards. Therefore, this test method is classified as a relative method (see ISO 16014-1).
