WebJan 1, 2015 · ROMP has a long history since the era of an early stage in Ziegler-Natta catalyst development; the first example for the ring-opening polymerization of cyclic olefin was demonstrated as a coordination polymerization of norbornene using a catalyst prepared from TiCl 4 in 1960, reported by Truett et al. . Web– Catalyst activity was too low to effect a reaction without a strong enthalpic driving force (ring- strain release in ROMP or entropic advantage of intramolecular reactions for RCM). – Product selectivity was low for the CM products. – Stereoselectivity was poor in the newly formed olefin.
