Polyamides are one of the major engineering thermoplastics. Their properties can be tuned by a number of techniques like copolymerization, incorporation of fillers, or blending with other polymers.1,2 The variety of polyamides offers a lot of industrial applications in textile, medicine, or automobile industry. In composite materials, some polyamides are considered nowadays as an alternative to epoxy or polyester thermosets as far as their properties and processing can be adapted for the production of parts at low price. Polycondensation and anionic ring-opening polymerization are the main methods used to prepare such materials.3,4 The need to find new synthesis methodologies is actual and is expected to propose new materials and properties. The discussion will focus on the combination of anionic ring-opening polymerization of ε-caprolactam and condensation polymerization of aminobenzoate derivatives for the synthesis of aliphatic-aromatic copolyamides.5 Thermal characteristics of some polyamides will be discussed.
