笔记 Notes: 聚氨酯-26是一种复合物的聚合物,是通过聚全氟乙氧基甲氧基二氟羟乙基醚与异佛尔酮二异氰酸酯(ipdi)反应形成预聚物而形成的。预聚物进一步与3-二乙氨基-1反应 Polyurethane-26 is a complex polymer that is formed by the reaction of Polyperfluoroethoxymethoxy Difluorohydroxyethyl Ether and isophorone diisocyanate (IPDI) to form a prepolymer. The prepolymer is further reacted with 3-diethylamino-1,2-丙二醇,然后用2-乙基-1-己醇封端任何残留的异氰酸酯基。所得聚合物用乙酸中和 2-propanediol followed by the capping of any residual isocyanate groups with 2-ethyl-1-hexanol. The resulting polymer is neutralized with acetic acid
