Hydrotalcite was modified by ultrasonicandion exchange method was added to isotaticpolypropylene (PP)materialssubsequently. X-ray diffraction spectra (XRD)
Fourier transform infrared spectroscopy (ATIR)
differential scanning calorimetry (DSC)
polarized light microscopy (POM)
scanning electron microscopy and other methods were used to characterize the effect of hydrotalcite on the structure of isotaticpolypropyleneby ultrasonicandion exchange method. These results indicated that the intercalation rate of modified groups can be promoted and increased
the dispersibilityofhydrotalcite in isotaticpolypropylenecan be improved by ultrasonic ion exchange method modified whichplays a distinct heterogeneous nucleation effecton isotaticPP
and the toughness of polypropylene material was simultaneously enhance by the refined grain.
