Abstract

This invention is directed to a polyamide-clay nanocomposite, products produced from the nanocomposite, and a process for preparing a polyamide-clay nanocomposite. The polyamide-clay nanocomposite comprises (a) an amorphous matrix polyamide comprising (i) a residue of a dicarboxylic acid component comprising at least two diacids and (ii) a residue of a diamine component, and (b) a layered clay material, wherein the layered clay material is dispersed in the matrix polyamide.
