Hydroxypolyamides, hydroxypolyamide products, and post-hydroxypolyamides are disclosed as gel forming agents. Hydroxypolyamides and post-hydroxypolyamides are prepared from known methods. Hydroxypolyamide products are produced from a modified polymerization procedure which utilizes strong base for deprotonation of ammonium salts from the esterification of stoichiometrically equivalent polyacid:polyamine salts. The hydroxypolyamide products are capable of gel formation at lower concentrations than hydroxypolyamides and post-hydroxypolyamides from the known methods of preparation, and are therefore superior gel forming agents.
本发明公开了羟基聚酰胺、羟基聚酰胺产品和后处理羟基聚酰胺作为凝胶形成剂。羟基聚酰胺和后处理羟基聚酰胺是通过已知的方法制备的。羟基聚酰胺产品是通过改进的聚合程序制备的,该程序利用强碱去质子化酯化反应中的聚酸:聚胺盐的
铵盐。羟基聚酰胺产品能够在较低浓度下形成凝胶,比通过已知制备方法制备的羟基聚酰胺和后处理羟基聚酰胺更为优越,因此是优良的凝胶形成剂。
