Abstract

Polyamides can be defined as polymers with reoccurring units linked by —NR—CO— groups.(1) They can be either synthetic or naturally occurring polymers. This chapter will be limited to discussions pertaining to synthetic polyamides or nylons. Polyamides can be classified into groups according to their base monomer types.(1–10) Polyamides made by the condensation of diacids and diamines (or suitable derivatives) represent the first group and are referred to as AA-BB polyamides (e.g., nylon 6–6). Those which are derived from condensed amino-acid structures constitute the second group and are usually referred to as A-B polyamides. They can be prepared from amino acids (e.g., polybenzamide and nylon 11), by lactam ring opening (e.g., nylon 6), or from unsaturated monomers by a hydride transfer mecha nism (e.g., nylon 3). Typical examples of the different types of polyamides and general routes for their synthesis are summarized in Table 1.
