1.前言聚合物分子量及分子量分布是高分子材料最基本的参数之一,与材料的物理力学性能密切相关。Moore 提出的凝胶渗透色谱(GPC)可便利地测定聚合物的各种分子量及分布。70年代末国外开发的高效 GPC 仪大部份配置单板机形式的数据处理系统,可自动进行色谱峰面积归一化和计算分子量。但高分子试样组份常常多于两个,GPC 谱图具有双
1. Introduction Polymer molecular weight and molecular weight distribution of polymer materials is one of the most basic parameters, and the physical and mechanical properties of the material are closely related. Gel Permeation Chromatography (GPC) by Moore makes it easy to determine the various molecular weights and distributions of polymers. The highly efficient GPC instrument developed overseas in the late 1970s most of the configuration data processing system in the form of single-board, can automatically peak area normalization and molecular weight calculation. However, the number of polymer sample components is often more than two and the GPC spectrum has double
