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.
氢氧基聚酰胺、氢氧基聚酰胺产品和后处理氢氧基聚酰胺被披露为凝胶形成剂。氢氧基聚酰胺和后处理氢氧基聚酰胺是从已知方法制备的。氢氧基聚酰胺产品是通过改进的聚合程序生产的,该程序利用强碱去质子化酯化的
化学计量等量聚酸:聚胺盐。这些氢氧基聚酰胺产品能够在比已知制备方法中的氢氧基聚酰胺和后处理氢氧基聚酰胺更低的浓度下形成凝胶,因此是优越的凝胶形成剂。
