摘要
本文以硝酸铈铵为引发剂,研究了丙烯酸丁酯与罗布麻纤维的接枝共聚反应规律及产物的物理性能。当铈离子浓度为6.5×10^(-3)~14×10^(-3)mol/L,单体浓度为0.7×10^(-1)~1.2×lO^(-1)mol/L,氢离子浓度为7×10^(-2)~1O×10^(-2)mol/L,40℃,反应3h,可以得到较高接枝率。接枝纤维断裂伸长比纯纤维有所提高,改善了柔顺性。
Graft copolymerization of butyl acrylate onto bluish dogbane fiber with Ce^(4+) as initiator was carried out in a heterogeneous system. The maximum grafting percentage was obtained at [Ce^(4+)] 6.5×10^(-3)~14×10_(-3) mol/L, [M] 0.7×10^(-1)~1.2×10^(-1) mol/L, [H+] 7×10^(-2)~1O×10^(-2) mol/L and at 40 °C within 3h of graft copolymerization.
