Abstract
ABSTRACTThe monomer N‐allyliminodiacetic acid (ALD) has been synthesized and grafted onto polyamide 6.6 multifilament yarns to develop metal chelate–forming fiber using benzoyl peroxide (BPO) as an initiator. The grafting yield depends on critical parameters, such as the monomer ALD concentration, initiator BPO concentration, pH, temperature, and reaction time. Suitable conditions that give the highest graft yield are reported. The modification occurred on the polyamide 6.6 fibers by grafting is evaluated by several techniques such as Fourier transform infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, thermogravimetric analysis, and scanning electron microscopy. © 2013 Wiley Periodicals, Inc.
