<正>Ziegler and Natta won the Nobel Prize in 1963 due to their contributions in olefin polymerization catalysis. Subsequent studies into related catalysts have led to a multibillion-dollar polyolefin industry. Currently, more than 178 million tons of polyolefin materials are produced annually, which constitute more than half of global plastics production. Interestingly, the metal nickel was initially recognized as a ‘‘poison" for olefin polymerization. Alkyl aluminum species can oligomerize ethylene(degree of polymerization
