This article represents the synthesis and characterization of polyamic acids and polyimides derived from several bifunctional amines with ethylenediaminetetraacetic acid (EDTA) anhydride using polyaddition followed by chemical/thermal imidization methods. The structural and thermal properties of the obtained polyamic acids and their six-membered cyclic polyimides were determined in detail by using FT-IR, TGA, and DSC analysis. Additionally, this method was also extended to synthesis of networked polyamic acid and polyimide using trifunctional amine and EDTA anhydride.
