Polyphthalamides are a class of polymers used in several components of automobile engines and are produced using benzene-1, 4-dioic acid and an aliphatic diamine. The repeating unit for the polyphthalamide that uses hexane-1, 6-diamine is to be drawn. Concept introduction: Step-growth polymerization occurs when molecules throughout a mixture join with any other molecule that has an appropriate functional group available to react, whether it is a monomer unit or another polymer molecule. The reaction mixture contains two different compounds, each of which has two reactive functional groups . The two monomers are linked together in the first step. The reaction continues, and the chain length increases because the product also has two reactive functional groups. Each of those functional groups can therefore produce another group. As the reaction progresses, long chains may join, greatly increasing the size of the chain in a single step.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
