Step 1

This structure suggests a polymer made from a monomer that has an amine (-NH2) group and a carboxylic acid (-COOH) group, due to the presence of an amide linkage (-NH-CO-) in the repeat unit. This is indicative of a condensation polymerization mechanism. Show more…

The repeat unit structures of three polymers, labeled (I) - (III), are shown below. For each polymer, write down the name of the polymer, the chemical structures of the monomer(s) from which the polymer could be prepared, and classify them according to their polymerization mechanism.
