    "content": "The synthesis of hydrophilic polymers involves monomers such as diols or diamines reacted with di-carboxylic acid esters, which upon sulfonation or quaternization enhance hydrophilicity; these functional groups increase interactions with water by incorporating hydrophilic characteristics directly into the polymer backbone, rather than as pendant groups, allowing for better water absorption and reducing interfacial tension.The monomers used in synthesizing hydrophilic polymers include acrylic acid and methacrylic acid, which contain carboxylic acid functional groups that enhance hydrophilicity by allowing for hydrogen bonding with water molecules.Monomers used for synthesizing hydrophilic polymers include diols such as ethylene glycol and neopentyl glycol, which possess hydroxyl functional groups that enhance hydrophilicity by forming hydrogen bonds with water, and carboxylic acids like dimethylol propionic acid (DMPA), which contains carboxylate ions that provide ionic character, stabilize aqueous dispersions, and act as internal emulsifiers.The monomers used for synthesizing hydrophilic polymers include hydrophilic additives with functional groups such as acid or salt of a polyalkylene oxide, which enhance hydrophilicity through the presence of ethylene oxide and propylene oxide repeat units that facilitate interactions with water through hydrogen bonding and increased solubility.Functional groups such as ethoxy groups in ethoxylated trimethylpropane triacrylate and the hydroxyl groups in poly(ethylene glycol) monomethacrylate enhance the hydrophilicity of polymers by increasing their ability to form hydrogen bonds with water, thus improving interactions with water.The text excerpt does not provide specific monomer structures or detailed information about functional groups that enhance the hydrophilicity of the corresponding polymers.The synthesis of hydrophilic polymers involves monomers such as polyethylene glycol (PEG), which possesses hydroxyl (-OH) functional groups that enhance hydrophilicity by forming hydrogen bonds with water, thereby improving interactions with aqueous environments.The synthesis of hydrophilic polymers involved the use of monomers such as tri-functional aziridine crosslinkers and PEG-based diacid, which contain functional groups such as carboxylic acid and amine groups, enhancing hydrophilicity through their ability to form hydrogen bonds with water molecules.The synthesis involved monomers such as 900-DA and PZ-2382, which contain functional groups that enhance hydrophilicity through increased hydrogen bonding and dipole interactions with water.The hydrophilic polymers were synthesized using monomers such as aziridine (PZ-2382 and PZ-502) which possess functional groups that enhance hydrophilicity through their ability to form hydrogen bonds with water, thus increasing interactions with water and contributing to the excellent anti-fog performance of the coatings.The monomer structures used for synthesizing hydrophilic polymers include polyalkylene oxide backbones terminating with acid or salt groups, which enhance hydrophilicity through the presence of carboxylate functional groups that strongly interact with water due to their ability to form hydrogen bonds and ionic interactions."
