Ring-opening metathesis polymerisation

Type of chain-growth polymerisation reaction involving cyclic olefins

In polymer chemistry, ring-opening metathesis polymerization (ROMP) is a type of chain-growth polymerization involving olefin metathesis. The driving force of the reaction is relief of ring strain in cyclic olefins. A variety of heterogeneous and homogeneous catalysts have been developed. Most large-scale commercial processes rely on the former while some fine chemical syntheses rely on the homogeneous catalysts. Catalysts are based on transition metals such as tungsten, molybdenum, rhenium, rubidium, and titanium.
