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%). © 2011 Wiley Periodicals, Inc.
