Define polymers as macromolecules built from repeating monomer units and describe the common properties of plastics (low density, flexibility, poor conductivity, chemical resistance) in terms of their long-chain structure and intermolecular forces.
The displayed formula below shows part of the chain of an addition polymer. (i) Deduce the structural formula of the monomer used to build this polymer. (ii) Describe one chemical property responsible for this type of polymer being a useful material.
(i) Hexanedioic acid reacts with hexane-1,6-diamine, . State the type of polymer that is formed. (ii) Draw one repeating unit of the polymer's structure.
