AB - Summary: High‐impact isotactic polypropylene (hiPP) is a multiphase material and hiPP is susceptible to stress‐whitening (or blushing) when exposed to impact, tension etc. Stress‐whitening will influence the quality of the products. The object of this work is to find the factors influencing the resistance of stress whitening. Five reactor‐alloy hiPP samples were used. Stress whitening was characterized by Gardner‐type impact apparatus. Automated PP viscometer and xylence solubles analyzer (CrystEX), tapping mode atomic force microscopy (TMAFM), Fourier transform infrared spectroscopy (FTIR), dynamic mechanical analysis (DMA), wide angle X‐ray diffraction (WAXD), differential scanning calorimetry (DSC) were used to characterize the samples. The stress‐whitening was found to be related with the following factors: 1.particle size of the dispersion phase (rubber phase), 2.composition of the dispersion phase, 3.crystallization in in the dispersion phase, 4.crystalline form of the matrix (iPP).
