Abstract
An improved process for synthesizing a sterically unhindered trifunctional primary amine is provided. This process includes the steps of slowly adding a particular unsaturated diester to a solution of a certain diamine in an aromatic organic solvent, and recovering the desired compound. The trifunctional primary amine is useful as a crosslinking agent.
