Abstract

Abstract: The graft copolymerization of methyl acrylate(MA), ethyl acrylate (EA), and butyl acrylate (BA) onto flax fibres using KPS-TUas redox initiation system has been studied. The structure of the grafted fibres was characterized by means of IR, SEM, and X-ray diffraction. The highest grafting percentage was obtained when [KPS]=1.5×10^-2mol/L, [TU]=2.0×10^-3mol/L, [M]=3.0×10^-1mol/L, [H⁺]=1.0×10^-2mol/L, S:L=1:50 and at 60℃ in 2h. The grafting reactivity order of the monomers is BA>EA>MA.

Key words: Flax fibres, Acrylates, Graft copolymerization
