    "content": "The monomers used for synthesizing hydrophilic polymers in the anti-fogging agent composition include sulfonic acid type amphoteric surface active agents and nonionic surface active agents, where the sulfonic acid functional group enhances hydrophilicity by providing ionic interactions with water, leading to improved solubility and adsorption on surfaces, especially when combined with inorganic salts or acetates that exhibit a salting-in phenomenon, dramatically increasing interactions with water.The synthesis of hydrophilic polymers includes monomers such as maleic anhydride and vinyl alcohol, which possess functional groups that enhance hydrophilicity through increased water interaction, as these polar functional groups can form hydrogen bonds with water molecules, thereby improving the polymer's affinity for water.The hydrophilic polymers are synthesized using monomers that contain sulfonic acid functional groups, which enhance hydrophilicity by increasing the polymer's ability to interact with water through charge interactions and hydrogen bonding."
