| 摘 要： | 以玉米淀粉为原料,(NH4)2S2O8为氧化剂,采用一步氧化法对淀粉氧化降解,进而与乙烯基类单体接枝共聚,制备了乙烯基类单体接枝共聚改性淀粉,并应用于蓝湿革复鞣工艺。结果表明,当(NH4)2S2O8用量为7.5%、降解温度为95℃、降解时间为30min时,共聚物的接枝率、接枝效率和单体转化率较高,且共聚物对坯革具有一定的复鞣填充和捕获游离甲醛的作用。FT-IR、XRD和TGA结果表明乙烯基类单体已成功接枝于氧化降解淀粉分子上。 |
| 关 键 词： | 淀粉 乙烯基类单体 氧化降解 接枝改性 复鞣 甲醛 |

| Abstract: | Grafted copolymer of oxidized starch and vinyl monomers was prepared using corn starch as raw material and(NH4)2S2O8 as oxidant,and it was applied in the retanning of chrome-tanned goatskin leather.The results show that grafted copolymer with higher percentage of graft(G),higher graft efficiency(GE) and higher monomer conversion(CM) could be obtained when the dosage of oxidant was 7.5%,the temperature of degradation was 95℃and degradation time was 30min.The grafted copolymer had retanning and filling effects,it could capture free-formaldehyde.FT-IR,TGA and XRD show that vinyl monomers had grafted into the molecules of degraded starch successfully. |
| Keywords: | starch vinyl monomers oxidative degradation grafted retanning formaldehyde |
