In the present study, 3-(Methacryloylaminopropyl) trimethylammonium chloride, acrylamide and N-cyclohexylacrylamide monomeric unit containing hydrogels were synthesized by free radical copolymerization using MBA as cross-linker APS as initiator in methanol/water medium at 600C. The synthesized hydrogel was confirmed by IR spectroscopy. The XRD analysis indicated that the hydrogel exhibited more amorphous and less crystalline in nature. SEM analysis showed sponge like morphology. TGA analysis showed double stage decomposition and stability up to 270OC. The swelling behavior of hydrogels increased with increasing amount of MPTMACl content. At higher content of MPTMACl, the swelling rate decreased due to the extent of cross linking occurring during the synthesis of hydrogel. The effect of temperature on swelling increases with increasing temperature up to 30OC and then decreased due to reduction in segmental mobility of polymeric chain at higher temperature.
