Ring-opening metathesis polymerization (romp) is a type of olefin metathesis chain-growth polymerization that produces industrially important products the driving force of the reaction is relief of ring strain in cyclic olefins (eg norbornene or cyclopentene)a variety of heterogeneous and homogeneous catalysts have been developed.
Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes in that same year the grubbs group proved that metathesis polymerization of norbornene by tebbe's reagent is a living polymerization system. Olefin metathesis  involves two olefin substrates which form a four-membered ring intermediate (first proposed by chauvin) and then rearrange the substituents to form two new carbon-carbon double bonds ring-opening polymerization metathesis. Ring opening metathesis (polymerization) - rom(p) strained rings may be opened by a ruthenium carbene-catalyzed reaction with a second alkene following the mechanism of the cross metathesis. Olefin metathesis is one of today's most promising technologies element in synthesis strategies for the construction of many organic compounds and the production of materials such as polymers and fine chemicals description.

Ring-opening metathesis polymerization (romp) uses metathesis catalysts to generate polymers from cyclic olefins. We demonstrated tandem ring-opening/ring-closing metathesis (ro/rcm) polymerization of monomers containing two cyclopentene moieties and postmodification via insertion polymerization in this system, well-defined polymers were efficiently formed by tandem cascade ro/rcm reaction pathway. Since the discovery of olefin metathesis in the mid-1950s, there has been great interest in using this versatile reaction to synthesize macromolecular materials.
