Synthesis and characterization of Poly(potassium, 3-sulfopropyl acrylate-acrylic acid) Hydrogels

Polymer gels swell in suitable solvents but cannot dissolve because of their network structure. Gels can be classified into two main groups: hydrogels and organogels [1].Hydrogels can be used in tissue engineering, drug delivery, diapers, contact lenses, agriculture, medical devices, etc [2].In the present work, we synthesized and characterized a series of copolymeric gels based on potassium, 3-sulfopropyl acrylate(KSPA) and acrylic acid(AA).
