高效凝胶渗透色谱法测定对叔丁基酚醛树脂的分子量及其分布

Determination of Molecular Weight and Molecular Weight Distribution of a p-tert-Butyl-Phenolic Resin with GPC

本文用日立635高速液相色谱仪对缩醛法制得的对叔丁基酚醛树脂的分子量及其分布进行了测定.以树脂低聚物峰为标样,标定了 GPC 柱,得到了分子量与流出体积的关系曲线.

The molecular weight and molecular weight distribution of a p-tert-butyl-phenolic resin obtained from 'Acetal Method' have been measured with GPC.A calibration curve of logarithm of molecular weight as a function of elution volume can be drawn with the peaks of low molecular weight resin compounds as standards.
