    "protocol": "1. Prepare a mixture of monomers consisting of (A1) vinyl monomers with N-hydroxymethyl or N-alkoxy hydroxymethyl groups, (A2) vinyl monomers with sulfonic acid groups, and (A3) (methacrylic) alkyl ester monomers. 2. Use a weight ratio where the total weight of (A1), (A2), and (A3) is 100 parts by weight, with (A1) in the range of 3 to 20 parts, (A2) in the range of 3 to 20 parts, and (A3) in the range of 60 to 94 parts, such that the total of (A1) and (A2) is between 6 and 40 parts. 3. For every 100 parts of the copolymer (A), include a surfactant (C) in the range of 0.5 to 30 parts by weight. 4. The basic compound (B) should be included in an amount corresponding to 50 to 95 mol% relative to the sulfonic acid group of (A2). 5. Optionally, include N,N-dialkyl(methacrylamide) monomer (A4) in the mixture, with 5 to 50 parts by weight for (A4) when accounting for the total of (A3) and (A4) being 100 parts by weight. 6. Ensure the basic compound (B) has a dissociation constant in aqueous solution at 25 degrees Celsius between 3 and 14 and a boiling point between 130 and 150 degrees Celsius. 7. The copolymer (A) should exhibit a crosslinked structure formed by a condensation reaction of the N-hydroxymethyl or N-alkoxy hydroxymethyl groups from (A1) and include both neutralized and unneutralized sulfonic acid groups from (A2) to enhance hydrophilicity and promote the condensation reaction.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。共聚物（A)的合成步骤：首先，准备包含单体（A1，N-羟甲基或N-烷氧基羟甲基的乙烯基类单体）、单体（A2，具有磺酸基的乙烯基类单体）和单体（A3，（甲基）丙烯酸烷基酯类单体）的单体混合物。按比例将单体（A1）和单体（A2）各3至20质量份，单体（A3）60至94质量份混合，使得单体（A1）和（A2）的总量为6至40质量份。加入N，N-二烷基（甲基）丙烯酰胺类单体（A4），比例为5至50质量份。然后，将碱性化合物（B）与磺酸基比例设为50至95mol%。最后，加入表面活性剂（C），比例为0.5至30质量份。混合物在适宜的条件下进行聚合反应，得到的共聚物（A）具有良好的亲水性和耐热性，且能够在高湿度和低温条件下固化。1. 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（如正丙醇）、单体（A1）N-羟甲基丙烯酰胺、单体（A2）2-丙烯酰胺-2-甲基丙磺酸、单体（A3）甲基丙烯酸烷基酯类单体以及可选的单体（A4）N,N-二甲基丙烯酰胺。2. 加入碱性化合物（B），如三乙醇胺，其用量为单体（A2）的磺酸基的50-95 mol%。3. 将自由基聚合引发剂加入反应容器中，进行聚合反应，聚合时间为5小时，升温至80°C聚合1小时，以获得共聚物溶液。4. 调节共聚物的浓度，加入表面活性剂，并混合以制备防雾涂料组合物。5. 使用喷涂法将防雾涂料组合物涂布于基材上，随后进行干燥及加热固化。"
