Chain walking gives a metal-alkyl complex. This process, a step in the chain walk, moves the metal from the end of a chain to a secondary carbon center. At this stage, two options are available: (1) chain walking can continue or (2) a molecule of ethylene can bind to reform the 16e complex. At this second resting state, the ethylene molecule can insert to grow the polymer or dissociate inducing further chain walking. If many branches can form, a hyperbranched topology results. Chain walking In polymer chemistry, chain walking or chain running is a mechanism that operates during some alkene polymerization reactions.
