Polyamides were prepared by reacting 3,5-diamino benzoic acid (DAB) and/or 1,3-bis( 3-amino benzamido) benzene ( ABB ) with terephthaloyl chloride in N,N-dimethylacetamide. Five polymer samples having different contents of pendant carboxyl groups were prepared by changing the molar ratios of DAB : A

## Abstract **Summary:** For industrial polymer applications, the structure‐property relation during thermal treatment is of high interest. If a polymer is degraded, its molecular structure will alter, and its mechanical properties are affected as well; thus limiting the usability. The objective of
