Ring opening metathesis polymerization (romp) catalytic process ⇒ efficacy of process is dependent on catalyst polymer is also dependent on monomer structure. Communication highly efficient ring-opening metathesis polymerization (romp) using new ruthenium catalysts containing n-heterocyclic carbene ligands. Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. Abstract olefin metathesis polymerization, in particularly ring-opening metathesis polymerization (romp), has been a popular topic of modern research.
