    摘要： Disclosed are a macrocyclic carbodiimide (MC-CDI) and a process for synthesizing the same through condensation of a molecule with multiple-isocyanate terminal functional groups under high dilution in the presence of a phospholene catalyst such as phospholene or arsenic catalyst. Also disclosed are MC-CDI derivatives, such as MC-urea (MC-U), MC-acylurea (MC-ACU), acid functionalized MC-ACU, and anhydride functionalized MC-ACU, processes for synthesizing the same, and the applications of such derivatives as hydrolysis stabilizers in organic polymeric materials, such as polyurethane (PU) and polyesters, as well as the applications in the syntheses of the amide- and imide-modified polyurethane by ring-opening reaction of the MC-ACU.
