描述了基于Passerini反应的多组分聚合。以二元羧酸、一元醛和二异氰酸酯为原料，采用一锅法合成了一种新型的序列可控的聚酯酰胺。证实了该聚合反应为逐步聚合机理，并对所得聚合物进行了表征，确定其为主链重复单元为酯酰胺的线性聚合物。当使用功能醛时，可以容易地同时引入功能侧基，为进一步的修饰提供了简单的途径。
Multicomponent polymerization based on Passerini reaction is described. Room temperature polymerization of dicarboxyl acid, monoaldehyde, and diisocyanide leads to the formation of a new type of sequence regulated poly(ester-amide)s in an efficient one-pot process. The polymerization was confirmed to be a stepwise mechanism, and the resulting polymers were characterized and determined to be linear polymers with a sequence regulated backbone repeating unit of esteresteramideamide. When functional aldehydes were used, functional side groups could be easily introduced at the same time, providing a simple way for further modification.
