Abstract—The current study describes the synthesis and characterization of poly (anilineco-metanitroaniline) using different mineral acids. Poly (aniline co-meta nitro aniline) was created at room temperature using the chemical oxidative polymerization of monomer aniline and co-monomer meta nitro aniline. As a dopant, hydrochloric acid, sulfuric acid, and perchloric acid were utilized, coupled with acrylic acid as a soft templet. Analytical techniques such as FTIR, UV- DRS, and XRD were used to analyze the synthesized Poly (aniline co - Meta nitro aniline).
