ABSTRACT:
A novel process for the preparation of injection moldable polymers prepared from diacylated aliphatic diamines, tricarboxylic anhydride compounds and aliphatic primary diamines. These polymers are useful for the preparation of injection molded articles and fibers. A process for enhancing the crystallization of these polymers by the addition of nucleating agents is also disclosed.
