| Abstract: | Relative molecular mass and its distribution of waterborne polyurethane resin were determined by high performance gel permeation chromatography(HPGPC) with HP PL gel MIXED-B dual-column system in series and ultraviolet absorption detector. Tetrahydrofuran solution was used as a mobile phase. Chromatographic conditions were optimized. The determined results were in agreement with those obtained by viscometry. The method can supply some help to understand the properties of waterborne polyurethane resins and to guide their productive technology and basic research. |
