【Abstract】 MAH is grafted on PP powder surface by using the method of UV irradiation solid phase with BP as photosensitizer. The grafting degree, which is influenced by factors of the concentration of photosensitizer, reaction temperature, reaction time and so on is studied. The grafted PP is characterized by means of FT IR, XPS and chemical titration qualitatively and quantitatively.更多还原
