THERMAL DEGRADATION STUDIES AND ANTIMICROBIAL ACTIVITIES OF NOVEL SASF COPOLYMER FOR INDUSTRIAL APPLICATIONS

Abstract

SASF copolymer was synthesized by polycondensation of Sulphanilic acid (0.2 mol), Semicarbazide (0.1 mol) and Formaldehyde (0.3 mol) in 500 mL RB flask using 1M hydrochloric acid as a catalyst. This mixture was kept for about 5 hours at 120⁰C which finally converted into resinous product. To characterize the synthesized copolymer using different spectroscopic tool like FTIR spectra, proton NMR spectra, XRD, SEM, and TGA. Resulting product was then studied by various analytical techniques such as Elemental composition, molecular weight determination by non-aqueous conductometry titration method and solubility in organic and inorganic solvents. The morphology of copolymer was examined by scanning electron microscopy (SEM). The studies have been additionally reached out to non- isothermal thermogravimetric examination (TGA) for assurance of their method of disintegration and relative thermal stability. Actuation energy (????????), order of reaction (????), and frequency factor (????) were determined by Sharp-Wentworth and Freeman-Carroll techniques. Actuation energy determined by Sharp Wentworth and Freeman-Carroll techniques are in close concurrence with one another. Activation energy of SASF copolymer was found to 15.6 kJ/mole and order of reaction was estimated as 0.82. SASF copolymer seen to be thermally stable and potent antimicrobial activity against four parasites.
