    "content": "The hydrophilic polymers synthesized in this coating composition are derived from a polyurethane having ethylenically unsaturated functional groups and include an isocyanate-reactive surfactant, which enhances hydrophilicity by chemically bonding within the polymeric network, thus improving water interaction through increased surface wettability.The synthesis of hydrophilic polymers involves the use of isocyanate-reactive components having ethylenically unsaturated functional groups, such as hydrophilic alkoxylated acrylates, which enhance hydrophilicity and contribute to permanent anti-fog properties by providing crosslinkable acrylate functionality that allows for better interactions with water through hydrogen bonding and polar interactions.The synthesis of hydrophilic polymers includes ethylenically unsaturated functional groups such as reactive vinyl groups, reactive acrylate groups, reactive methacrylate groups, and reactive allyl groups, which enhance interactions with water due to their ability to form hydrogen bonds and increase polarity, thereby improving hydrophilicity.The polyols used for synthesizing hydrophilic polymers include diols and triols with main chain segments of polyethylene oxide and polypropylene oxide, containing functional groups such as ethylene glycol, propylene glycol, and polyethylene oxide, which enhance the hydrophilicity of the polymers by increasing their ability to form hydrogen bonds with water molecules.The monomers used for synthesizing hydrophilic polymers include hydroxyl groups, thiol groups, amine groups, and ethylenically unsaturated functional groups like acrylates, which enhance the hydrophilicity of the polymers by increasing their capacity to form hydrogen bonds with water molecules, thereby improving their interaction with water.The synthesis of hydrophilic polymers involved the use of monomers such as trimethylolethane, ethylene glycol, and polyethylene glycol, all of which contain hydroxyl functional groups that enhance hydrophilicity by forming strong hydrogen bonds with water, thereby improving the interaction of the polymer with water.The synthesis involves functional groups like the hydroxyl group from 4-hydroxybutyl acrylate that enhance the hydrophilicity of the resulting polymers by forming strong hydrogen bonds with water, thus improving water interaction and absorption.The synthesis of hydrophilic polymers involves the use of monomers such as ethylene glycol, which contains hydroxyl (-OH) groups that enhance hydrophilicity by forming hydrogen bonds with water molecules, and 4-hydroxybutyl acrylate, which also has hydroxyl groups contributing to water interaction through similar hydrogen bonding mechanisms.The monomers used for synthesizing hydrophilic polymers include acrylic acid and polyethyleneglycol diglycidyl ether, with functional groups such as carboxyl (-COOH) in acrylic acid and ether (-O-) in polyethyleneglycol enhancing hydrophilicity by promoting hydrogen bonding and dipole-dipole interactions with water molecules.The isocyanate-reactive component having ethylenically unsaturated functional groups comprises an isocyanate-reactive alkoxylated acrylate, which includes hydroxyl groups that enhance hydrophilicity by promoting hydrogen bonding interactions with water."
