Development and Application of Oxidatively Degradable Polymer Prepared by Utilizing the Properties of Hydrazide

以双酰肼为原料合成了聚二酰肼和聚酰氨基脲。这些聚合物是有用的可氧化降解的聚合物：虽然每种聚合物在空气中即使在较高温度下也是稳定的，但它在次氯酸钠溶液的作用下迅速分解。采用双酰肼氧化偶联聚合法直接合成了聚双酰肼。侧链上带有酰肼的聚合物通过选择性氧化可逆交联和解交联。

Poly(diacylhydrazine) and poly(acylsemicarbazide) were prepared from bishydrazide. These polymers were useful oxidatively degradable polymers : Although each polymer was stable in air even at higher temperature, it decomposed rapidly by the action of sodium hypochlorite solution. Poly(diacylhydrazine) was directly prepared by the oxidative coupling polymerization of bishydrazide. Polymers with hydrazide in the side chain reversibly crosslinked and decrosslinked by the selective oxidation.
