摘要
介绍了高效凝胶渗透色谱法测定苯乙烯改性醇酸树脂料的相对分子质量及其分布. 选用 P Lgel M L X E D B 柱,四氢呋喃作流动相,示差折光检测器来测定相对分子质量及其分布,相对分子质量范围为3250000 ~580 u ,方法有较好的精度.
The high performance gel permeation chromatography is used for the study on relativem olecular mass and its distribution of styrene m odified alkyd resin paint using three Plgel mixed Bcolu m ns (300 ×Φ7 5 m m) in series . With tetrahydrofuran as the mobile phase ,eluates were moni tored with a H P1047 Differential Refracto meter Detector . The relative molecular mass is rangedfro m 3250000 ~580u . The precision of the method was inspected .
