Another form of nylon that uses only one monomer unit (not two). This monomer is difunctional with a carboxylic acid group at one end and an amine group at the other. The condensation reaction between two such molecules produces an amide bond in the same way as the synthesis of Nylon 66. The monomer used is (I think) 7-amine-1-heptanoic acid.
