    "content": "Hydrophilic polymers are synthesized using monomers that contain functional groups such as hydroxyl groups (-OH), amino groups (-NH2), carboxyl groups (COOH), and sulfonic groups (-SO3H), which enhance their hydrophilicity by strongly interacting with water molecules and having a high capacity to absorb water.The monomers used for synthesizing hydrophilic polymers include 2-hydroxyethyl methacrylate (HEMA) and 2-acrylamido-2-methyl propane sulfonic acid (AMPS), which contain hydroxyl and sulfonic acid functional groups, respectively; these functional groups enhance hydrophilicity by promoting hydrogen bonding and ionic interactions with water molecules.The monomers used for synthesizing hydrophilic polymers include HEMA and AMPS, with functional groups such as sulfo groups and hydroxyl groups that enhance hydrophilicity by promoting hydrogen bonding and ion-dipole interactions with water."
