P11 EFFECT OF SYNTHESIS DURATION ANDTEMPERATURE ON THE SYNTHESIS AND PROPERTIES OFPOLYANILINE AND POLY(ANILINE-co-m-AMINOBENZOIC ACID)E.N. Zahar, A. Alimuddin, N.

By increasing thetemperature and synthesis duration, the incorporation of m-ABA increased. ATR-FTIR spectroscopy indicated the copolymerization of aniline and m-ABA had takenplace. The amount of reacted m-ABA in variable synthesis duration and temperatureswere determined by UV-Vis spectrophotometry and elemental analysis. The amountsof reacted m-ABA also increased as the synthesis duration and temperature increased.The conductivity increased to 1.05 Scm -1 for CP 2:1 and 1.56 Scm -1 for polyaniline asthe polymerization temperature decreased to 0°C. The conductivity is increased to1.01 Scm -1 for CP 2:1 as the polymerization time shortened, and prolonged thesynthesis duration gave a higher conductivity for polyaniline which is 4.55 Scm -1 . Inthis study, the optimized condition of synthesis duration and temperature toincorporate the copolymer were obtained.RHNRRNRHNHNHnWhere R = H for polyaniline= COOH and/or H for copolymer= COOH for p(m-ABA)26 |16 th Industrial Chemistry Seminar: Chemistry- A Passport to a Brighter Future
