Olefin polymerization based on late-transition-metal catalysts has been one of the most exciting developments in the area of catalysis, organometallic chemistry and polymer science in recent years.[1–3] Interest in polymers of cyclic olefins such as norbornene (NB)(bicyclo [2.2. 1] hept-2-ene) has increased dramatically because of the attractive properties of this addition type of polymer such as high chemical resistance, good UV ...
