General Introduction

Polyamides are defined as polymers containing amide linkages at monomer repeating units along main chains. They have been widely studied and commercialized since Ca­rothers of DuPont filed the first patents[‌1‌] in 1937 on synthetic polyamides, such as nylon-6,6, which is still one of the most important products and has a variety of uses. Poly­amides can be categorized into aliphatic (1), aliphatic–aromatic (2), and aromatic types (3) by the different sequences in their chemical structures, as shown in Scheme 1.
