Notes:
A series of polyamides and polyureas containing cyclic (1b, 1c, and 1d) or acyclic (2b, 2c, and 2d) bipyridinediyl diamino units in the polymer backbone were prepared. By introducing aliphatic or aromatic comonomers, it was possible to influence the degree of rigidity of the resulting polymers. In the synthesis of the polymers 2c and 2d two new azamacrocycles 5 and 6, respectively, were also produced and they were isolated and characterized. 1H-NMR and IR spectral data support the structure of the synthesized compounds. Thermal analysis data indicate that the polyureas posses lower PDT (polymer degradation temperature) values with respect to the corresponding polyamides.
