Ring-opening metathesis polymerisation. 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). A variety of heterogeneous and homogeneous catalysts ...
Ring-opening metathesis polymerization (ROMP) takes a cyclic alkene, splits open its double bond, and knitting it together with other cyclic alkenes to produce a long polymer chain with regularly spaced double bonds.
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.

Polymers are prepared by ROMP of norbornene derivatives M-137. Each of the six different phosphonium substituted monomers was polymerized with a target M n of 3 kDa and 10 kDa, with achieved molecular weights relatively close to the target values ( P-124 3.8–4.4 kDa and 9.4–15.5).
