    "protocol": "The synthesis of hydrophilic polymers involves the use of a copolymer (A) formed from a mixture of monomers A1, A2, and A3. Monomer A1 is a vinyl monomer with N-hydroxymethyl or N-alkoxy hydroxymethyl groups; monomer A2 is a vinyl monomer with a sulfonic acid group; and monomer A3 is an alkyl (meth)acrylate monomer. The total amount of monomers A1, A2, and A3 is 100 parts by mass, where A1 comprises 3-20 parts, A2 comprises 3-20 parts, and A3 comprises 60-94 parts, with the total of A1 and A2 being 6-40 parts. The base compound (B), which includes single or multiple amines such as monoethanolamine or diethanolamine, is used in an amount of 50-95 mol% relative to the sulfonic acid group of monomer A2. Surfactant (C) is included at 0.5-30 parts by mass relative to 100 parts of copolymer (A). Additionally, N,N-dialkyl (meth)acrylamide monomer (A4) can be included in the mixture, comprising 5-50 parts for a total of 100 parts with monomer A3. The copolymer A is shown to possess crosslinked structures formed through condensation reactions of monomer A1, while the neutralized and non-neutralized sulfonic acid groups in monomer A2 enhance the hydrophilicity of the copolymer.该加热固化型防雾涂料组合物含有嵌段共聚物或接枝共聚物，所述嵌段共聚物或接枝共聚物由亲水性聚合物部分与疏水性聚合物部分构成，所述亲水性聚合物部分由具有N-羟甲基、N-羟甲基醚基、羟基中的任一种交联官能团的单体、亲水性单体及（甲基）丙烯酸低级烷基酯形成，所述疏水性聚合物部分由具有磺酸基、羧基或磷酸基的乙烯基类单体及（甲基）丙烯酸低级烷基酯形成。在具有搅拌装置、氮气导入管及冷凝管的反应容器中加入聚合溶剂的正丙醇（240g），以及单体（A1）N-羟甲基丙烯酰胺（10g），单体（A2）2-丙烯酰胺-2-甲基丙磺酸（10g），单体（A3）甲基丙烯酸甲酯（60g）和丙烯酸正丁酯（20g），单体（A4）N,N-二甲基丙烯酰胺（20g），以及碱性化合物（B）三乙醇胺（5.04g）。边吹入氮气边加热至65°C。将自由基聚合引发剂的过氧化新戊酸叔己酯的烃稀释品（1g）溶于40g正丙醇中，然后在3小时内滴入反应容器中。聚合5小时后，将反应容液升温至80°C，在该温度下聚合1小时，得到共聚物浓度为30质量%的溶液。然后在该共聚物溶液中加入NPA和丙二醇单甲醚（400g），使共聚物浓度调整至10质量%；接着加入表面活性剂（C）2-乙基己基磺化琥珀酸钠（10g）和流平剂（0.1g），混合得到防雾涂料组合物。涂饰时，将防雾涂料组合物涂布于基材上，干燥后在60-150°C条件下加热固化5-60分钟，形成涂膜。"
