Synthesis, Characterization, and Thermal Degradation process of Poly-4

Abstract

Schiff base polymer [P-4-HMPIMP] of 4-[(4-hydroxy-2-methylphenyl) imino-methyl]-2, 6-dimethylphenol (4-HMPIMP) was synthesized via oxidative polycondensation reaction in an alkaline medium with using NaOCl, H 2 O 2 or air as oxidants. The structures of the synthesized monomer and polymer were confirmed by FT-IR, UV-Vis, NMR and elemental analysis, while their properties were characterized by TG-DTA, size exclusion chromatography (SEC) and solubility tests. The influence of the type of oxidizer on M n, M w and PDI values was also studied. Conductivity measurements of the polymer was done by electrometer using four point probe technique and the electrochemical and optical band gap values of both 4-HMPIMP and P-4-HMPIMP were determined by using cyclic voltammetry and UV-Vis measurements. Conductivity and band gap values indicate that this polymer is a typical semiconductor.
