Formation of an open coordination site
- The mechanism of ROMP is similar to any olefin metathesis reaction. Initiation occurs by formation of an open coordination site. Propagation occurs via a metallacyclobutane intermediate.

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 (e.g. norbornene or cyclopentene).
Ring-opening metathesis polymerization (ROMP) is a chain growth polymerization process where a mixture of cyclic olefins is converted to a polymeric material (see Fig. 1 for an illustrative example) [3].
The ring-opening metathesis polymerization (ROMP) process provides very high chain controllability in developing well-defined macromolecules. The ROMP initiator enables the complex structure synthesis with desired functionality.
Jan 1, 2015 · Ring-opening metathesis polymerization (ROMP) is a form of chain-growth polymerization based on the olefin metathesis reaction which converts cyclic olefins to unsaturated polyalkenamers.

In polymer chemistry, ring-opening polymerization (ROP) is a form of chain-growth polymerization in which the terminus of a polymer chain attacks cyclic monomers to form a longer polymer (see figure). The reactive center can be radical, anionic or cationic.
ROMP mechanism. The driving force for the polymerization is typically the release of some ring strain in the cyclic monomer, leading to an enthalpy driven polymerization. One of the earliest commercial applications of ROMP was the polymerization of dicyclopentadiene, as shown in Scheme 10.
Apr 11, 2017 · Stages of ROMP. The initiation begins with the coordination of the cycloolefins’ double bond with the metal-carbene complex. The next step is a formation of a metal-cyclobutane intermediate. This process occurs in each act of addition of the monomer during the chain growth.
