Abstract

In this research, the graft copolymerization of methyl methacrylate/2-hydroxypropyl methacrylate (MMA/2-HPMA) onto poly(ethylene terephthalate) fibers was studied using 4,4-azobis-4-cyanovaleric acid (ACV) as a radical initiator. The synergistic effect was found to be at its highest quantity when an MMA/2-HPMA mixture having 40 % methyl methacrylate (wt %) was used. The grafting was improved the moisture region of the fibers. The effect of different parameters, such as initiator, monomer mixture concentrations, reaction time and temperature were studied. Optimum condition were determined to be [ACV] = 4 × 10-3 M, t = 45 min, T = 85 °C and [MMA/2-HPMA] = 0.2 M. The rate of grafting was calculated to the 1.29 power of monomer mixture and 1.71 power of initiator. The overall activation energy for grafting was determined as 44.95 kJ/mol. The grafting fibers were characterized by Fourier transform infrared, scanning electron microscopy, thermo gravimetric analysis.
