TL;DR: In this paper, the role of the cyclo-olefin for reducing the tungsten compounds and producing the metallacarbene species is outlined, and the sharp influence of strongly complexing additives on the reaction kinetics, catalyst activity and on the evolution of molecular weight with time in the polymerization of cyclopentene is presented.

TL;DR: In this paper, three distinct ESR signals were recorded during the polymerization of cyclopentene in the presence of the WCl6/epichlorohydrin/i-Bu3Al system.
