metathesis polymerization

https://doi.org/10.1351/goldbook.08992
Polymerization in which unsaturated monomers are transformed into unsaturated polymers by a process of bond redistribution.
Notes:
  1. Metathesis polymerization is most often metal-catalyzed and the kinetic-chain carriers alternate between metal-carbene complexes and metallacyclobutanes or between metal-carbyne complexes and metallacyclobutenes.
  2. The two most common forms of metathesis polymerization are ring-opening metathesis polymerization (ROMP) and acyclic diene metathesis polymerization (ADMET). ADMET is not a chain polymerization.
