abstract

  • In order to further improve the anti-aging properties of polypropylene (PP), the polypropylene (PP) was modified via Supercritical carbon dioxide (SC CO2) grafting copolymerization with AN. PP-g-AN characterized by FT-IR. Polypropylene grafted acrylonitrile (PP-g-AN) / polypropylene (PP) / silica (SiO2) were blended. The influence of the contents of PP-g-AN on the anti-aging property was discussed. At the same time, the anti-aging mechanism was studied. After the artificial accelerated ageing test, the result shows that the anti-aging properties of PP were improved greatly which due to the addition of PP-g-AN and SiO2
