笔记 Notes: 聚氨酯-24是通过以下多步合成制得的复合物聚合物。第一 Polyurethane-24 is a complex polymer prepared via the following multi-step synthesis. First, 异佛尔酮二异氰酸酯(ipdi)与三种不同的多元醇反应 isophorone diisocyanate (IPDI) is reacted with three different polyols: 聚(1 Poly(1,4-丁二醇)-30 4-Butanediol)-30, 1,4-丁氧基-2 4-Butanediol, 邻氨基苯甲酸顺-3-己烯基酯(3z)-己-3-烯-1-基-2-氨基苯甲酸酯(z)-己-3-烯基-2-氨基苯甲酸酯(z)-己-3-烯基邻氨基苯甲酸顺式-hex-3 -邻氨基苯甲酸酯[(z)-己-3-烯基] 2-氨基苯甲酸酯hex-3(顺式)-邻氨基苯甲酸酯(3z)-3-己烯-1-醇2-氨基苯甲酸酯(z)-3-hexen-1- 2-氨基苯甲酸酯3-己烯-1-醇 and dimethylol butanoic acid. This pre-polymer is then reacted with a reagent formed by the reaction between Aminpropyl Triethoxysilane and lauryl acrylate. The resulting polymer is subsequently chain extended by reaction with isophorone diamine in aqueous solution to produce Polyurethane-24
