In-situ copolymerization of aniline with alkyl amine by APS:Kinetics and application

Polymer Research Laboratory, Department of Chemistry, Aligarh Muslim University, Aligarh 202002, India

Received Date: 31 March 2008

The kinetic study of in-situ copolymerization of aniline with o-and p-methylaniline by ammonium persulfate (APS) has been carried out.UV-vis spectroscopic method was used to investigate the course of copolymerization.Structural characterization was studied by FT-IR spectral analysis.The electronic spectra of the copolymers poly(aniline-co-p-toluidine) and poly(aniline-co-o-tolnidine) show blue shift.The shift has been observed in the bands corresponding to π→π^* transition as well as in the exciton transition.The increase in absorbance recorded during the reaction for different concentration of aniline,o-and p-toluidine at various intervals of time of polymerization reaction indicates a growth in the polymer formation.The resulting first-order rateconstant was used to calculate the rate of copolymer formation using the rate equation-d[A]/dt=kcⁿ.
