ABSTRACT:
A process is disclosed for the production of linear amorphous polyamides which results in polyamides having more amine endgroups than acid endgroups. It comprises condensing an aqueous solution of salts comprising at least one aromatic diacid containing from 7 to 20 carbon atoms and a greater than equimolar amount of at least one aliphatic diamine containing from 4 to 20 carbon atoms.
