What is the repeating unit of nylon?
The repeating unit of nylon is a polymer made up of amide linkages, typically derived from the condensation of diamines and dicarboxylic acids. For example, in nylon 6,6, the repeating unit consists of hexamethylenediamine and adipic acid, resulting in a structure containing six carbon atoms in each segment. This amide bond formation contributes to the strength and durability of nylon as a material.
