MAH is grafted on PP powder surface by photoinitiated solid phase graft copolymerization with BP or MK as photosensitizer.The grafting degree
which is influenced by factors of the concentration of photosensitizer
reaction temperature
irradiation time
and surface treatment of PP is studied.The grafting extent and crystal structure of MAH_gPP are characterized by XPS
WAXD and FT IR.Results indicated the grafting degree increases with the concentration of MK
the preferred reaction temperature is 24℃.After plasma treating and the first-grafting of PP surface
the adsorption of the monomer on PP surface increases.The contact state between the monomer and PP macromolecule is improved and the grafting degree is increased also.
