摘要
In this article, ultrasonic degradation of copolymers--poly (3\|hydroxybutyrate\|co\|hydroxyvalerate) (PHBV) was first re ported. Effect of reaction conditions on the degradation rate was investigated. By ultrasonic irradiation w e find that copolymers with narrower molecular weight distributions and higher purity can be obtained in a s hort time and chain cleavage takes place at HV block.
