Abstract

Macroazonitriles containing crown ether moieties and various amounts of N  Nunits in the main chain were prepared by solution polycondensatio between cis‐diamino dibenzo‐18‐crown‐6 (DADC) and adipoyl chloride (AC) or terephtaloyl chloride (TPC) with the addition of 4,4′‐azobis(4‐cyanopentanyl chloride) (ACPC). Decomposition of the azo linkage present in the polyamides, obtained by using TPC, were studied by DSC. The rate constants and activation energies for the decomposition were determined and a small effect of terephtaloyl group on the rate was observed. The kinetics of the polymerization of styrene by the poly(azoamide), obtained from ACPC and DADC were investigated in DMSO.
