When 1,3,5,7-cyclooctatetraene undergoes ring-opening metathesis polymerization in dilute solution, benzene is formed irreversibly in 75% yield. Benzene formation is insignificant in bulk metathesis polymerization. Considering the mechanism of metathesis polyerizationm, suggest a reason for the different behavior
