    "content": "The monomer used for synthesizing the hydrophilic polymer includes ureido groups, which enhance hydrophilicity due to their hydrogen bonding capabilities with water, as well as poly(ethylene oxide) ether segments that increase the polymer's affinity for water through increased surface hydration and decreased surface tension.The text mentions that hydrophilic polymers are often synthesized from low-adhesion oligomers such as polyethyleneglycol acrylate or polyurethane acrylate, which contain functional groups that may improve hydrophilicity; however, these oligomers typically lack rich functional groups, leading to poor adhesion.The monomers used for synthesizing hydrophilic polymers include urea groups and polyethylene glycol ether, which enhance hydrophilicity through functional groups that provide better wetting properties and facilitate interactions with water, ultimately improving adhesion to substrates by utilizing low surface tension and permeability to swell in substrates.The monomers used for synthesizing hydrophilic polymers include tri(2-hydroxyethyl) isocyanurate triacrylate (THEICTA) and hydroxyethyl acrylate (HEA), which contain functional groups such as hydroxyl (-OH) that enhance the hydrophilicity of the corresponding polymers by facilitating hydrogen bonding and increasing interactions with water."
