| 摘 要： | 研究了用KMnO_4/H_2SO_4作为引发剂,聚酯(PET)纤维与丙烯酸接枝共聚的改性方法,探讨了间甲酚浸泡时间和温度、KMnO_4浓度、H_2SO_4浓度、丙烯酸(AA)浓度等对接枝率的影响。结果表明:间甲酚浸泡时间2h、浸泡温度60℃、KMnO_4浓度3.0×10~(-3)mol/L、H_2SO_4浓度0.02mol/L、AA浓度2.66mol/L、反应时间2h时,PET纤维的接枝率较高;同时,用红外光谱证明了聚丙烯酸接枝支链的存在。

| Abstract: | The graft copolymerization modification of polyester fiber and acrylic acid (AA) was studied with KMnO4/H2SO4 as an initiator. The effects of soaking time and temperature in m-cresol, KMnO4 concentration, H2SO4 concentration and AA concentration on graft yield were discussed. The results showed that the higher graft yield of polyester fiber can be obtained under the conditions as followed: soaking time 2 h and temperature 60℃ in m-cresol, KMnO4 concentration 3.0 × 10-3 mol/L, H2SO4 concentration 0.02 mol/L, AA concentration 2.66 mol/L, reaction time 2 h. The graft fiber was characterized by IR spectrum. |
