| Abstract: | Vapor phase grafting of vinyltrimethoxysilane(VTMS) onto polypropylene(PP) powders and its subsequent hydrolysis crosslinking were studied in this work.The vapor grafting mechanism of VTMS onto PP through free radical was studied.The effects of the VTMS monomer and initiator concentrations on the grafting degree of the silane and gel content of the crosslinked samples were investigated.FTIR and FTIR-PAS were used to analyze the grafted materials.The result shows that the diffusion conditions of the monomer and the(initiator) in the PP have significant influence on the VTMS grafting degree.The grafting degree of VTMS(increases) with increasing monomer and initiator concentrations,and this trend slows down when the concentrations of the monomer and the initiator are over 0.026 mol/L and 0.6%,respectively. |
