Not leaving anything to chance : Rapid and reversible exchange between “tight” and “loose” ion pairs was used to modulate the relative reactivities of ethene and 1‐hexene or cyclopentene in a programmed fashion for living coordination chain‐transfer polymerization. Thus, different grades of a monodisperse polyolefin copolymer, such as the poly(ethene‐ co ‐1‐hexene) samples shown, could be obtained with a single cationic transition‐metal catalyst.
