通过凝胶渗透色谱法(GPC)分析醇酸树脂对涂料性能的影响

摘要

通过凝胶渗透色谱法(GPC)分析不同种类及不同生产工艺的醇酸树脂对醇酸涂料性能的影响.指出应根据需要,选择相对分子质量及其分布适宜的醇酸涂料树脂.%The influences of different types and the different synthesis process of alkyd resin on the paint performances were analyzed by GPC. It is pointed out that appropriate relative molecular weight of alkyd resin and its distribution should be selected according to the needs.
