    "content": "The monomers used for synthesizing hydrophilic polymers include polyethylene glycol, poly(vinyl alcohol), polyvinyl acetate, and polyvinylpyrrolidone, which contain functional groups that enhance hydrophilicity, such as hydroxyl (-OH) or ether (-O-) groups, allowing for strong interactions with water through hydrogen bonding and increased surface wettability.The synthesis of hydrophilic polymers involves monomers such as polyvinylpyrrolidone (PVP) which contains a pyrrolidone group that enhances hydrophilicity through its ability to form hydrogen bonds with water, thereby increasing interactions and affinity for moisture."
