Surface Graft Polymerization of Binary Monomers Maleic Anhydride/n-Butyl Vinyl Ether on the Polypropylene Film via Two-Step Method

Abstract: ABSTRACT:Maleic anhydride (MAH) was readily grafted onto polypropylene (PP) film by means of introducing the electron donor monomer n-butyl vinyl ether (n-BVE), via two-step method. In the first step, the semibenzopinacol (SBP) groups were introduced onto the film surface under UV irradiation, and they were subsequently detected by both gravimetric method and UV spectra. In the second step, the "dormant" SBP groups were activated and cleaved from the substrate under heat, resulting in the formation of surface … Show more

“…Over the past decade, extensive investigations in our group have been focused on the development of novel photopolymerization systems. Reinitiation from dormant sites derived from active hydrogen abstraction of benzophenone (BP) or isopropylthioxanthone (ITX) and coupling of semipinacol or thioxanthpinacol radicals with surface macroradicals have been demonstrated. Through such a reinitiation, free radical polymerizations with living/controlled characteristics were performed, giving rise to the immobilization of monolayered or multilayered nanoparticles on polymer film surfaces .…”

“…Some reports have shown that living radical polymerization allows graft polymerization onto shaped polyolefin substrates without shape changes 22–25. These reports show that a lengthy process is necessary before the introduction of initiators for ATRP graft polymerization 22–25. None of these reports have discussed the number of introduced initiators.…”

“…The introduction of graft chains onto polyolefin substrates such as polyethylene (PE) or polypropylene (PP) by living radical polymerization has been known to be difficult, because these are chemically inert surfaces when compared to silicon surfaces. ATRP initiators have been introduced onto the surfaces of the polyolefin substrates by ultraviolet irradiation and block copolymer chains grafted onto the substrates 18–21. However, the structures of the monomers for this method are limited, and it is particularly difficult to graft water‐soluble monomers, because the surface of the polyolefin substrate is hydrophobic.…”
