Abstract
A thermoplastic polyamide can be obtained through the reaction of at least the components (i), (ii), and (iii), where a catalyst having a Lewis base component is used in the reaction. Component (i) is a composition containing a polymeric compound having two carboxylic acid moieties; component (ii) is a dicarboxylic acid composition containing at least one dicarboxylic acid; and component (iii) is a diisocyanate composition containing at least one diisocyanate. A process can be used for producing the thermoplastic polyamide and a method for the use thereof. A tandem reactive extruder can be used for the reaction.
