Metathesis polymerization

{
  "id": "MLC-T-CHM-007272",
  "term": "Metathesis polymerization",
  "field": "Chemistry",
  "definition": "A polymerization in which unsaturated monomers become unsaturated polymers through redistribution of carbon-carbon double bonds, usually catalysed by metal carbene complexes of tungsten, molybdenum or ruthenium. Ring-opening metathesis polymerization of cyclic olefins is a chain polymerization, whereas acyclic diene metathesis polymerization proceeds by step growth and releases ethene.",
