Abstract

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.
