Plastics—Determination of average molecular mass and molecular mass distribution of polymers using size-exclusion chromatography—Part 4:High-temperature method
IDT ISO 16014-4:2012
全国塑料标准化技术委员会(SAC/TC 15)
GB/T 36214的本部分规定了在60 ℃~180 ℃下使用有机洗脱剂，通过体积排除色谱法(SEC)测定聚合物平均分子量和分子量分布的方法。依据聚合物标样构建的校正曲线计算得到平均分子量和分子量分布，因此该测试方法属于相对法(参见附录A及GB/T 36214.1—2018的附录A)。
