Abstract
Cleavage and polymerization with the same catalyst: The catalyst system named in the title, which cleaves polyethylene and polypropylene under a hydrogen atmosphere, is also capable of polymerizing ethylene or propylene. This shows the close relationship between olefin insertion and β‐alkyl elimination [Eq. (a), (P)=polymer chain(P)].Keywords
