    "protocol": "The synthesis of the hydrophilic polymer involves mixing elongated colloidal silica with a mixture of silane derivative compounds. This silane derivative mixture must include at least one compound with a polyethylene glycol chain and one compound with an epoxy group. Additionally, the silane derivative compounds may contain acyl or carbamate groups. The optimal amount of the silane derivative mixture, relative to 100 parts by weight of the solid component of elongated colloidal silica, should be between 0.1 and 10.0 parts by weight. The synthesis may include spherical colloidal silica and the elongated colloidal silica can be a mix of acidic and basic types.本发明的实施方式中的防雾涂料组合物的特征在于含有：长条状胶体氧化硅；及硅烷衍生物化合物混合物，其至少包含分子内具有聚乙二醇链的硅烷衍生物化合物及分子内具有环氧基的硅烷衍生物化合物。将酸性长条状胶体氧化硅、碱性长条状胶体氧化硅、分子内具有聚乙二醇链的硅烷衍生物化合物、分子内具有环氧基的硅烷衍生物化合物、表面活性剂及有机溶剂加以混合而制作防雾涂料组合物。合成氨基甲酸酯硅烷A的步骤包括向茄型烧瓶中加入3‑异氰酸基丙基三甲氧基硅烷和Uniox M-400，在75°C下搅拌10小时，通过1H-NMR确认源自异氰酸基的峰消失，得到氨基甲酸酯硅烷A。其余氨基甲酸酯硅烷B、C、D的合成步骤类似，以不同的原料和氧化硅混合物的调配量为基础。"
