Routes for the formation of HCN-derived polymers. The reaction schematic illustrates the formation of HCN-derived polymers using different monomer units, including HCN itself, aminoacetonitrile H2N-CH2-CN (AAN), iminoacetonitrile (IAN), aminomalononitrile (AMN) and diaminomaleonitrile (DAMN). The routes explored in this study are highlighted (*). HCN, hydrogen cyanide.
