Zusammenfassung:	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.
