water dispersible polyamide, water dispersible polyamide, process for forming a water dispersible polyamide building block, and reaction product.

摘要

Water dispersible polyamides with carboxylic acid groups are described. they are made by reacting polycarboxylic acids or anhydrides thereof with amine containing monomer or an amide terminated polyamide under reaction conditions such that some of the carboxylic acid groups are residual and may promote dispersion in water. These post-dispersion polyamides may be chain extended to higher molecular weight polymers or may 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 described and claimed.
