Synthesis and spectral study of 2, 4-Diaminophenol based copolymer

Abstract

Abstract A copolymer resin was synthesized by condensation polymerization reaction of 2,4-diaminophenol, Oxamide and formaldehyde with 2N NaOH as a catalyst. The purification of copolymer was carried out by precipitation technique and column chromatography. The purified copolymer resins were confirmed by Infra-red, 1H and 13C-NMR spectroscopy. Further formation of copolymer has been confirmed by Mass Spectrometry. The surface morphology of copolymers was established by Scanning Electron Microscopy (SEM). Degradation of synthesized copolymer were performed by Thermogravimetric Analysis (TGA). The stability is observed as up to 473 K and complete mass loss was observed up to 1173 K.
