摘要：

Breaking up and making up: The ultrasonic cleavage of high-molecular-weight linear coordination polymers of phosphane telechelic polytetrahydrofuran and palladium dichloride in dilute solution is a reversible process (see picture). Sonication for 1 h led to a decrease in the weight-averaged molecular weight of the polymer from 1.7 × 105 to 1.0 × 105 g mol-1. Upon leaving the sample to stand for 24 h, the original molecular weight was completely restored.
