Abstract: This invention relates to high molecular weight toluenediamine-containing polyamide resins formed by the reaction of a mixture of 2,4-toluenediamine and 2,6-toluenediamine and derivatives thereof with an aromatic diacid or precurser thereof. The resulting polyamides are amorphous, as opposed to crystalline. Because they are amorphous, they lend themselves to a wide variety of processing techniques and because of their high molecular weight, they have outstanding physical properties.The polyamides are prepared using a precondensate method wherein a mixture of the toluenediamine isomers and aromatic acid, usually in the form of the aromatic acid dihalide, is reacted at relatively low temperatures forming a precondensate and the precondensate subsequently polymerized in the presence of an acid acceptor.
