Effect of linear polyacrylamide on the properties of semi–IPN hydrogels based on N, N’–Dimethylacrylamide, and maleic acid

In this work, the semi–interpenetrating polymer network hydrogels based on Polyacrylamide; N, N’–Dimethylacrylamide, and Maleic acid were synthesized and investigated by changing the content of linear polyacrylamide in the obtained materials. The chemical properties, morphology, swelling behaviors in distilled water, and mechanical properties of the hydrogels were investigated.
