Abstract :

In this work, we prepared co-hydrogel with two monomers of vinyl pyrolidone and vinyl sulfonic acid by free radical polymerization metod and azobisisobutyronitrile (AIBN) is a initiator ,and N,N-methylen ebisacryl amide is an crosslinker agent in 65ċ and 5 hours and 45 minutes.we synthesized co-hydrogel 1:1,1:0.5,1:0.25 mol ratio on feed composition. there for we obtain amphiphilic hydrogels. for invistigation of complexation behavior between two monomer (cationic and anionic monomer) we used uv spectroscopy. there for, we invistigation of swelling properties of synthesized co-hydrogels (amphiphilite hydrogels)in different PH 1,4,7,10,12 also we obtaine ratio amount of swelled hydrogel.
