  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.

  本文披露了一种大环碳二亚胺（MC-CDI）及其合成方法，通过在高稀释条件下，在磷烯或砷催化剂的存在下，将具有多个异氰酸酯末端官能基的分子进行缩合反应来合成MC-CDI。还披露了MC-CDI衍生物，如MC-脲（MC-U）、MC-酰脲（MC-ACU）、酸官能化的MC-ACU和酐官能化的MC-ACU，以及其合成方法，以及这些衍生物作为有机聚合材料（如聚氨酯（PU）和聚酯）中的水解稳定剂的应用，以及在通过MC-ACU的环开反应合成酰胺和亚酰胺改性聚氨酯的合成中的应用。
