To propose the steps for the formation of vestenamer and norsorex by olefin metathesis polymerization . Concept introduction: Vestenamer and norsorex can be obtained by the olefin metathesis polymerization. An olefin metathesis reaction can be stated as the reaction between two molecules ( alkenes ) by exchanging their substituents on their double bonds. The catalyst used for olefin metathesis polymerization is Grubb ’s catalyst (it contain a carbon-metal double bond and have a genral structure as M=CH-R. The function of Grubb’s catalyst is to react reversibly with an alkene to form a four membered cyclic compound knowa as metallacycle. Here, “M” is Ru i.e. ruthenium. Metallacycle opens up in the next step to give rise to different alkene and a different catalyst. Vestenamer , is produced by cyclooctene by the process of ROMP (Ring openeing polymerization process) , also known as TOR (trans-polyoctenamer) . It is also used as an blending material to impart greater elasticity and durability to other rubbers. Norsorex is also known as 90% of the trans polymer of norbene with a very high molecular weight. It was the first comercial metathesis polymer. It is sold as a molding powder and the final vulcanized product is used in various fittings in the vehicle.

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
