Abstract
The poly(N-tert-amylacrylamide-co-acrylamide/AcNa)hydrogel was synthesized by free radical copolymeristion in water/methanol medium using Ammonium per sulphate as the initiator and N,N-methylenebisacrylamide as a crosslinker at 60oC.The amount of N-tertamylacrylamide(NTA) and Acrylamide(AM) were fixed and the amount of sodium acrylate was varied.The Hydro gels were characterized by 1H-NMR ,13C-NMR and IR Spectroscopy.The swelling behavior of hydrogels was studied by gravimetric method and degree of swelling was increased by increasing the amount of AcNa.The surface morphology was studied by SEM analysis. Keywords: N-tert-amylacrylamide,AcNa,Hydrogels,Swelling behavior
