  "term": "Zwitterionic polymerisation",
  "field": "Chemistry",
  "definition": "A chain polymerization in which the growing macromolecule carries two ionic chain carriers of opposite charge, one cationic and one anionic, at one or both ends. It starts when a neutral nucleophile, such as an N-heterocyclic carbene added to a lactone, attacks the monomer, or when a nucleophilic and an electrophilic monomer react with each other, so no external ionic initiator is needed.",
