ROMP has become an important reaction for the formation of well defined polymers. Ziegler and Natta's early studies on ethylene and polypropylene polymerization lead to extensive research efforts on the investigation of transition metal catalyzed polymerization and its mechanism, which ultimately lead to the development of ROMP.
