制备了偶氮功能化聚乙二醇的超声诱导位点特异性裂解。在聚合物主链中，超声解理速率更快。结果表明，偶氮功能化聚合物具有高度的键特异性，导致链端类型单一，片段的多分散性较低。结果表明，超声诱导的聚合物位点特异性裂解可以作为热和光诱导反应的替代方法。
The ultrasonically induced site-specific cleavage of azo-functionalized poly (ethylene glycol) was fabricated. It was observed that the rate of ultrasonic cleavage is faster in the polymer backbone. It was found that the azo-functionalized polymer cleaves with a high degree of bond specificity, resulting in one type of chain end and fragments of low polydispersity. The results show that ultrasound-induced site-specific cleavage of polymers could be extended as an alternative to thermal and photoinduced reactions.
