| 摘 要： | Photoinduced grafting of acrylic and allyl monomers on polyethylene surface wasgenerally studied by using benzophenone (BP) as a photoinitiator. The grafting process wascarried out either in vapor-phase or in solution of the monomers. In the vapor-phase reactionwith a filter used to cut off the short wavelength UV light, allyl amine is the most reactive ofthe four monomers used and acrylic amide is comparatively more reactive than acrylic acid andallyl alcohol. Acetone, as a solvent and carrier for initiator and monomers, however, showsits reactivity to participate the reaction. The solution grafting with a filter is much faster thanthe corresponding vapor-phase reaction, and a fully covered surface by the grafted polymercan be achieved in this way.
