    • A water-soluble, cationic, thermosetting, polyureideepihalohydrin-formaldehyde resin condensate is formed by reacting a polyalkylene polyamine with urea to form a polyureide intermediate, quenching the polyureide-forming reaction, reacting the polyureide with epihalohydrin and finally reacting the polyureide-epihalohydrin intermediate with formaldehyde to form the water-soluble, cationic, thermosetting resin product. The product is useful as a wet-strength additive in paper and as the resin component in aqueous printing fluids which are, in turn, useful in the high speed printing or decorating of absorbent papers.
    • 通过使聚亚烷基多胺与尿素反应形成聚酰脲中间体,淬灭形成聚脲的反应,使聚酰脲与表卤代醇反应,最后使聚酰胺 - 表卤代醇反应形成水溶性阳离子,热固性聚酰亚胺 - 表卤代醇 - 甲醛树脂缩合物 中间体与甲醛形成水溶性阳离子型热固性树脂产品。 该产品可用作纸中的湿强度添加剂和水性印刷液中的树脂组分,这又可用于高速印刷或装饰吸收纸。
