尼龙-66与衣康酸的接枝共聚反应

Graft Copolymerization of Nylon-66 Fiber with Itaconic Acid

摘要: 以过硫酸钾／硫酸为引发剂，使尼龙-66纤维与衣康酸进行接枝共聚。研究了尼龙-66纤维接枝率与硫酸浓度、过硫酸钾浓度、衣康酸浓度、反应温度、时间和预处理时间之间的关系。实验结果表明，硫酸浓度为0．5mol／L，反应温度50℃，反应时间40h时，接枝率较高，预处理时间对接枝率也有较大影响。

Abstract: The graft copolymerization of itaconic acid (IA) onto nylon-66 fiber was investigated by using K_2S_2O_8 / H_2SO_4 as an initiator under different conditions. The copolymerization reaction is influenced by the concentrations of K_2S_2O_8 , IA and H_2SO_4,
