UpcomingPlastics—Determination of isotactic index for polypropylene (PP)—Low-resolution nuclear magnetic resonance spectrometry
塑料 聚丙烯（PP）等规指数的测定 低分辨率核磁共振波谱法
Application Summary AI generated
This standard specifies a method for determining the isotactic index of polypropylene (PP) using low-resolution nuclear magnetic resonance (NMR) spectrometry. It is applied in the plastics industry for quality control and material characterization of PP resins, particularly in manufacturing and testing contexts where rapid, non-destructive measurement of polymer tacticity is required. The method is suitable for production line monitoring and laboratory analysis of PP materials used in packaging, automotive parts, and consumer goods.
