Title: polyisocyanide Long Title: IUPAC Gold Book - polyisocyanide DOI: 10.1351/goldbook.15254 Status: current Definition Polymer prepared from an isocyanide. Notes 1) The class name polyisocyanide is preferably used for polymers in which every isocyanide monomeric unit contributes only one atom to a macromolecule backbone; the majority of these polymers are helical polymers. 2) Isocyanide monomers are also polymerized by cyclopolymerization to give polytriazines.
