    Abstract

    In this study, Psyllium and acrylic acid based polymeric networks were synthesized under different reaction conditions such as in-air, in-vacuum, and under the influence of γ-radiations using potassium persulphate (KPS)- hexamethylene tetramine (HMTA) as an initiator-crosslinker system. Initially, optimization of varied reaction parameters was performed under all the different reaction conditions. The synthesized networks were then characterized using FTIR spectroscopy, SEM, TGA/DTA, and XRD techniques. It has been found that the percent grafting varies with varying reaction conditions with maximum grafting (138 ± 1.15%) reported in case of synthesis carried-out in-vacuum followed by the synthesis in-air (125 ± 1.00%) and then in case of synthesis under the influence of γ-radiations (124 ± 1.15%).
