Graft copolymerization of acrylamide onto gum karaya using diode laser (532nm)

Author:Nafie A. AlMuslet, Elfatih Ahmed Hassan, Al Sayed Abd-El-Magied Al-Sherbini and Mohamed Gusm Alla Muhgoub

Abstract:
Graft copolymerization of acrylamide (AAm) on Gum Karaya GK using diode laser (532 nm) was investigated. The results showed that, the optimum conditions to achieve efficient graft copolymerization were: 60 minutes laser irradiation time and 0.5 gm of GK, 0.142 gm of acrylamide (monomer). The percentage of graft efficiency and percentage of graft yield were 28.00%, and 98.59%, respectively. The graft copolymers were characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Thermogravimetric analysis (TGA) and Scanning Electron Microscope (SEM) which proved a successful production of GK-g-AAm. Thus, Laser irradiation was found to be effective and clean method for producing GK-g-AAm.
