    "content": "The monomers used for synthesizing the hydrophilic polymers include functional groups such as amino (-NH2), hydroxyl (-OH), and sulfonyl (-SO2-), which enhance hydrophilicity by establishing hydrogen bonds and ionic interactions with water molecules, thereby improving water solubility and affinity.The text does not provide specific information regarding the structures of the monomers used for synthesizing hydrophilic polymers or details about functional groups that enhance hydrophilicity.The monomers used in synthesizing the hydrophilic polymer are DM and iPen, where functional groups such as amino groups in DM and hydroxyl groups in iPen enhance the hydrophilicity of the corresponding polymers by increasing their ability to form hydrogen bonds with water, thereby improving their interactions with the aqueous environment."
