摘要： Abou-Zeid等人曾报道以Fe(2+)-H2O2体系引发丙烯腈等单体与黄麻纤维的接枝共聚反应,Misra等人报道了以S2O8-2-TU为引发体系,甲基丙烯酸甲酯与黄麻纤维的接枝共聚,最近,我们报道了以Ce(Ⅳ)引发甲基丙烯酸甲酯、丙烯酸乙酯(EA)分别与苧麻及亚麻纤维的接枝共聚。亚麻纤维与丙烯酸酯类单体接枝改性后,仲长率有所提高,加强了结合力,改善了成纱品质,因此引起人们的重视。

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
