Abstract

In the present study ,a series of Poly(N-cyclohexylacrylamide -co –acrylamide / Sodium acrylate) Hydrogels were synthesized by free-radical copolymerization in Water/Methanol medium using Ammonium persulfate (APS) as the initiator and N,N-methylenebisacrylamide (MBA) as a crosslinker at 600C. The amount of N-cyclohexylacrylamide (NCA) and Acrylamide (AM) monomers was fixed and the amount of sodium acrylate(AcNa) was varied. The Hydrogels were characterized by IR spectroscopy. The swelling behavior of Hydrogels showed that the degree of swelling was increased with increasing the amount of Ac Na. The surface morphology indicated porous and well type structure.
