    摘要： An improved creping adhesive is prepared by first reacting a dibasic carboxylic acid, or its ester, half-ester, or anhydride derivative, with a polyalkylene polyamine, preferably in aqueous solution, under conditions suitable to produce a water soluble polyamide. The water-soluble polyamide is then reacted with an epihalohydrin until substantially fully cross-linked, and stabilized by acidification with phosphoric acid at the end of the polymerization reaction to form a water-soluble poly(aminoamide)-epihalohydrin creping adhesive that is re-wetable and facilitates water spray removal of buildup so as to lengthen the life of the creping blades, with attendant significant decrease in downtime and maintenance.

    摘要翻译： 通过首先使二元羧酸或其酯，半酯或酸酐衍生物与聚亚烷基多胺反应，优选在水溶液中，在适于生产水溶性聚酰胺的条件下进行改性来制备改进的起皱粘合剂。 然后将水溶性聚酰胺与表卤代醇反应直到基本完全交联，并在聚合反应结束时用磷酸酸化稳定，形成水溶性聚（氨基酰胺） - 表卤醇起皱粘合剂， 可润湿并促进水喷雾去除，从而延长起皱刀片的使用寿命，同时显着降低停机时间和维护时间。

    摘要： Cationic thermosetting resins and especially resins having azetidinium functional groups, such as polyamidoamine-epichlorohydrin resins, are stabilized against premature gelation by the addition of (1) a low molecular weight, non-aldehyde, non-ionic, water soluble organic stabilizing compound (preferably one that is reactive with the cationic moiety), preferably in combination with (2) a water soluble, inorganic complexing metal salt.
