UV‐vis spectroscopic data indicate that zirconocene cations with Zr‐bound allylic chain ends are generally formed during olefin polymerization with zirconocene catalysts. The rates and extent of their formation and of their re‐conversion to the initial pre‐catalyst cations depend on the types of zirconocene complexes and activators used.
