摘要: Chitosan (CTS) modification with polystyrene (PS) and poly(n-butyl acrylate) (PnBA) via nitroxide-mediated polymerization (NMP) a grafting from approach is reported. CTS was first functionalized glycidyl methacrylate (GMA) then converted into macroalkoxyamine by intermolecular 1,2 radical addition of either 2,2,5-trimethyl-3-(1-phenylethoxy)-4-phenyl-3-azahexane (TIPNO-based alkoxyamine the “Universal Alkoxyamine”, UA) or SG1-based BlocBuilder (BB) alkoxyamine. Graft polymerizations styrene n-butyl acrylate were conducted, using homogeneous media to ensure uniform onto backbone. The graft modified based materials analysed 1H-NMR, TGA FT-IR.
