Polyisocyanide

  "id": "MLC-T-CHM-009152",
  "term": "Polyisocyanide",
  "field": "Chemistry",
  "definition": "A polymer prepared from isocyanide monomers, in which each monomer contributes a single carbon atom to the backbone and that carbon carries a pendant imino group, so the repeat unit is C(=NR). Steric crowding of the side groups forces the chain into a rigid helix, and most polyisocyanides are helical polymers. Nickel(II) complexes are the classic catalysts for the polymerization.",
