✦ Synopsis

Copolyamides based on poly( m-phenylene isophthalamide) and poly-(p-phenylene terephthalamide), to which 1,6-diaminohexane units were regularly inserted every 3 or 5 phenylene monomer units, were synthesized. The copolymers were obtained by condensation of individually prepared diamino-and dicarboxylic-building blocks via the Yamazaki-Higashi reaction. Solubility of the copolyamides are discussed in relation with the structure.
