    "content": "The monomers used for synthesizing hydrophilic polymers included PBA (polybutylene adipate), which contains hydroxyl functional groups that enhance hydrophilicity, and BDO (1,4-butanediol), which also has hydroxyl groups; these functional groups enhance interactions with water by forming hydrogen bonds, thereby increasing the polymer's affinity for water.The functional groups identified in the synthesis of hydrophilic polymers include isocyanates, hydroxyls, and urethanes, where hydroxyl and urethane groups enhance hydrophilicity through hydrogen bonding and increased polarity, resulting in improved interactions with water."
