The efficiency and outcome of ROMP heavily depend on the type of catalyst used. Transition metal catalysts, such as those based on ruthenium, molybdenum, or tungsten, are commonly employed. These catalysts are crucial because they determine the reaction rate, the molecular weight distribution of the resulting polymer, and the stability of the active species during the polymerization process. A well-chosen catalyst can lead to high yields, control over polymer architecture, and high molecular weights.
