采用辐射接枝聚合的方法制备了一种新型的含4-氨基-1，2，4-三氮唑(ATZ)的无纺布纤维。为此，采用辐射引发接枝聚合方法，在乳液介质中将甲基丙烯酸缩水甘油酯(GMA)接枝到聚乙烯包覆的丙纶非织造布(NWF)上。优化了接枝条件，并用ATZ对接枝的GMA的环氧基团进行了改性。在不同的溶剂，即水和二氧六环/水的混合物中，分别加入不同浓度的氨基三唑(5%、10%、20%(w/w))，得到了最佳的改性条件。在80℃下，以10%(w/w)的ATZ溶液为溶剂，以二氧六环/水为溶剂，可获得最大的改性效果。(C)2013爱思唯尔有限公司。保留所有权利。
A novel 4-amino-1,2,4-triazole (ATZ) containing nonwoven fiber was prepared by means of radiation induced graft polymerization. For this purpose, glycidyl methacrylate (GMA) was grafted onto polyethylene coated polypropylene nonwoven fibers (NWF) in emulsion medium by using radiation induced graft polymerization. Grafting conditions were optimized and epoxy groups of grafted GMA were then modified with ATZ. Optimum conditions for modification were conducted in different solvents i.e. water and dioxane/water mixture at different amino triazole concentrations (5%, 10%, 20% (w/w)). Maximum modification was obtained in 10% (w/w) ATZ solution in dioxane/water mixture as a solvent at 80 degrees C. Prepared nonwoven fibers were characterized by FTIR and thermal analysis techniques.
