    "content": "The synthesis of hydrophilic polymers involves monomers with functional groups such as carboxylic acid esters, which enhance hydrophilicity by providing polar interactions with water, thus increasing the polymer's affinity for water.The text describes the use of polyether polyols containing sulfonic functional groups, which enhance the hydrophilicity of polyurethane polymers by allowing the sulfonic groups to react into the polyurethane main chain, thus improving water interactions without providing a clear separation between hydrophilic and hydrophobic segments, ultimately enhancing the water absorption and maintaining antifog properties.The synthesis of hydrophilic polymers involves monomers with functional groups such as hydroxyl (-OH) and carboxyl (-COOH) that enhance hydrophilicity; these groups increase interactions with water through hydrogen bonding, thus resulting in improved water absorption and stability of the resulting polymers.The information provided does not include specific details about the functional groups in the monomers used for synthesizing hydrophilic polymers or explanations of how these functional groups enhance interactions with water.The hydrophilic polymers were synthesized using monomers such as 2-[甲氧基（聚氧乙烯）丙基]三甲氧基硅烷, PEG单甲醚, and ammonia salts based on PEG, with functional groups like hydroxyl (-OH), ether (-O-), and amine (-NH) that enhance hydrophilicity by increasing the polymer's ability to interact with water through hydrogen bonding and dipole-dipole interactions."
