【摘要】 以硝酸铈铵为引发剂,研究了甲基丙烯酸甲酯、丙烯酸乙酯分别与苧麻及亚麻纤维的非均相接枝共聚合反应规律。当[Ce⁴⁺]在4.5×10^-3～6.5×10^-3mol·l^-1、[M]在6×10^-1～9×10^-1mol·l^-1、[H⁺]在5×10^-2～8×10^-2mol·l^-1,30～40℃,反应2～3小时,接枝率较高。更多还原

【Abstract】 Graft copolymerization of methyl methacrylate （MMA） and ethyl acrylate （EA） onto ramie fibers and flax fibers with Ce（Ⅳ） as initiator was carried out in heterogeneous systems. The percent grafting （G%） was considerably affected by [Ce⁴⁺], [M],[H⁺] temperature and time. The better G% was obtained when [Ce⁴⁺] was 4.5×10^-3～6.5×10^-3 mol.l^-1,[M]6×10^-1～9×10^-1mol.l^-1, [H⁺] 5×10^-2～8×10^-2mol/l at 30～40℃ within 2～3h. A suitable over-all rate equation of grafting copolymerization has been derived.更多还原
