The molecular structure, crystalline morphology and comprehensive mechanical properties of six kinds of high impact polypropylene (PP) with high fluidity were studied in combination with the application of the resins by thermogravimetry (TG), Fourier transform infrared spectroscopy (FTIR), gel permeation spec-troscopy (GPC), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), polarized light microscopy (PLM), conventional mechanical properties testing, etc. The results show that the copolymerized PP grades AZ564 and K9026 have high fluidity with melt flow rate close to 30 g/10 min and notched Izod impact strength up to 10 kJ/m2. The relative molecular mass distribution and crystalline morphology of the two grades are relatively good.
