A novel Diels–Alder polymerization system was developed, using an azodicarbonyl compound as the dienophile. A bis(azodicarbonyl) monomer was prepared by quantitative oxidation of bis(diacylhydrazine) with tBuOCl in the presence of pyridine. Diels–Alder polymerization was carried out with a bisdiene monomer, using AgOTf as the catalyst. High thermal stability of the polymer is characteristic for the
使用偶氮二羰基化合物作为亲二烯体,开发了一种新型的Diels-Alder聚合系统。通过在吡啶存在下用t BuOCl对双(二酰基肼)进行定量氧化来制备双(偶氮二羰基)单体。Diels–Alder聚合反应是使用AgOTf作为催化剂,使用双二烯单体进行的。聚合物的高热稳定性是该Diels-Alder聚合体系产物的特征,其中Diels-Alder反应是不可逆的。Diels–Alder聚合物中的C = C键可以通过臭氧分解作用裂解成聚酮。
