Abstract
This invention relates to reactive liquid polyamides derived from poly-basic acids and amine residues obtained as by-products from the process for the hydrogenation of adiponitrile to hexamethylenediamine. By use of these amine residues it is possible to obtain liquid polyamide products having low amine values and manageable viscosities. The liquid reactive polyamides are useful for a variety of applications, for example, they can be blended with thermoplastic polyamide resins to impart desirable properties thereto.
