1. 
   Nylon 6
   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...

3. 
   Nylon 66
   A polymer widely used in a fibrous form in fabrics as well as solid lumps of plastic (e.g. in chopping boards and bearings). Nylon 66 may be formed from the condensation polymerisation of 1,2-hexadiamine and 1,8-octadioic acid, although modern industrial processes have improved upon these reactions ...
