    "content": "The monomers used for synthesizing hydrophilic polymers include N,N-dimethylaminoethyl methacrylate, which contains dimethylamino groups that enhance hydrophilicity through strong hydrogen bonding with water, and 1,3-propyl sulfonic acid lactone, which improves water interaction via its sulfonic acid group that increases ionic interactions with water molecules.The hydrophilic polymers synthesized from monomers such as acrylamide (AM), 2-acrylamido-2-methylpropane sulfonic acid (AMPS), and dimethyl diallyl ammonium chloride (DMDAAC) contain functional groups like sulfonic acid and ammonium groups that enhance hydrophilicity by promoting strong interactions with water through hydration and ionization, which increases their water retention and resistance to salt and temperature variations.The hydrophilic polymers synthesized in the method comprise methacryloxyethyl-N,N-dimethylpropanesulfonate and 4-vinylpyridine with functional groups such as sulfonate and quaternary ammonium, which enhance hydrophilicity through increased ionic interactions and hydrogen bonding with water.The synthesized hydrophilic polymers include methyl methacrylate-derived DMAPS (dimethylaminopropyl sulfonate) which features functional groups such as sulfonate that enhance hydrophilicity through strong ionic interactions with water, and VPPS (vinylpyridine propanesulfonate) which contains pyridinium and sulfonate groups that improve water affinity by facilitating hydrogen bonding with water molecules."
