The Network Formation Process in the Aqueous Free Radical Crosslinking Copolymerization of Acrylamide/ N, N-Methylenebis(acrylamide)

Polymeric hydrogels are widely used in various industries because of their significant volume changes they show in response to external stimuli [1, 2]. Acrylamide-basedhydrogels are the most important member of hydrogels family due to their unique properties such as thermal stability andmechanical strength and hence are used in enhanced oil recovery (EOR), plastic surgery, control drug delivery [3]. Studies [4] have shown that polymerization rate is highlydependent on parameters like initiator and solvent concentrations. In this research, we study, for the first time, the kinetics of acrylamide copolymerization through simultaneous gravimetric and dilatometric methods, and the effect of solvent content on the surface topology of gels
