| Abstract: | Bi-oriented polypropylene (BOPP) is a material for film production, and its molecular weight has significant effect on its processing and performance. The article introduced the direct determination of the molecular weight and its distribution of BOPP by using the high temperature gel chromatography system of differential and velocity bi-detectors, with narrow molecular weight distribution polystyrene as the standard for universal correction. The method has advantages of being easy, fast and accurate. |
