International Science Community Association Research Journal of Chemical Sciences 2231 - 606X 4 5 2014 May 18 Synthesis and Characterization of Poly Acrylic Acid Modified with Dihydroxy Benzene-Redox Polymer 1 9 EN Vetriselvi V 1 PG & Research Department of Chemistry, Auxilium College, Vellore, Tamil Nadu, INDIA Santhi.R R.Jaya 2 > Research Paper 2013 11 30 2014 May 18 Poly acrylic acid was functionalized with catechol, hydroquinone, catechol-hydroquinone, a homolytic modification by an oxidative decarboxylation using ammonium persulphate as an oxidant. The chemically modified PAA/Catechol, PAA/Hydroquinone and PAA/Catechol-Hydroquinone were characterized using UV and FT-IR. Thermal analysis shows PAA/Catechol, and PAA-Hydroquinone are stable above 700C and their Ea are lesser for PAA/Hydroquinone with the highest percentage of substitution than the other two polymers. The kinetic parameters were calculated from the TGA curves and the average molecular weight measured by viscometer was found to be around 1.1X10g/mol. From XRD studies the prepared polymers were found to be semi crystalline nature which is confirmed from the SEM analysis. The morphology of the redox polymer was found to be rod and cage like microstructure. From the CV studies, the potential difference was calculated.
