  A polyamide and/or polyimide is prepared by using N,N'- dimethylethyleneurea or N,N'-dimethylpropyleneurea as a solvent for polycondensation of a polycarboxylic acid and a diisocyanate at a temperature above 100°C in the presence of an alkali metal carbonate, alkali metal hydrogencarbonate, alkali metal hydroxide or an alkali metal salt of a polycarboxylic acid. Where an alkali metal salt of a polycarboxylic acid is employed, the salt is preferably of an acid having the same or a similar structure to the polycarboxylic acid participating in the polycondensation reaction.

  以 N,N'-二甲基亚乙基脲或 N,N'-二甲基丙基脲为溶剂，在碱金属碳酸盐、碱金属碳酸氢盐、碱金属氢氧化物或聚羧酸的碱金属盐存在下，在 100°C 以上的温度下进行聚羧酸和二异氰酸酯的缩聚反应，制备聚酰胺和/或聚酰亚胺。 在使用聚羧酸的碱金属盐时，盐最好是与参与缩聚反应的聚羧酸具有相同或相似结构的酸。

  Water dispersible polyamides having carboxylic acid groups are disclosed. These are made by reacting polycarboxyl is acids or anhydrides thereof with amine containing monomer or an amide terminated polyamide under reaction conditions such that a few of the carboxylic acid groups are residual and can promote dispersion in water. These polyamides after dispersion can be chain extended to higher molecular weight polymers or can be terminally functionalized with reactive groups such as isocyanate, epoxy, vinyl, acetoacetonate, or silanol groups. Composites and hybrids of these polyamides with vinyl polymers are also disclosed and claimed.

  本发明公开了具有羧酸基团的水分散性聚酰胺。这些聚酰胺是通过聚羧酸或其酸酐与含胺单体或酰胺末端聚酰胺在反应条件下进行反应而制成的，反应条件使少数羧酸基团残留并可促进在水中的分散。分散后的这些聚酰胺可以链延伸为更高分子量的聚合物，也可以用异氰酸酯、环氧树脂、乙烯基、乙酰丙酮酸酯或硅醇基团等活性基团进行端基官能化。此外，还公开了这些聚酰胺与乙烯基聚合物的复合材料和混合物。
