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 1.7×10 5 to 1.0×10 5 g mol −1 . Upon leaving the sample to stand for 24 h, the original molecular weight was completely restored.
