电子束辐射接枝制备弱碱性胺基阴离子交换纤维
|
摘要
通过电子束辐射聚烯烃纤维湿法非织布,接枝氯甲基苯乙烯制备苯乙烯无纺布,然后该接枝共聚无纺布进一步与胺化试剂二乙烯三胺反应,制备得到一种弱碱性胺基阴离子交换纤维。实验结果显示,辐射剂量越高,氯甲基苯乙烯单体浓度越大,纤维接枝率越高。同时,胺化时间越长,其转化率越高。
The styrene nonwoven fabric was prepared by graft copolymerization of chloromethyl styrene by electron beam radiation of polyolefin fibers,and then the graft copolymerization non-woven fabric was further reacted with amines of two ethylene three amine to prepare a weak alkaline anion exchange fiber.The experimental results showed that the grating rate of the fibers increased with the radiation dose and the concentration of chloromethylstyrene monomer.At the same time,the longer the amination time was,the higher the conversion rate was.
