Abstract

Terpolymeric ligand MAF has been synthesized by the condensation of melamine (M) and aniline (A) with formaldehyde (F) in the presence of an acid catalyst in 1:2:4 molar proportions of the reacting monomers. The characterization of terpolymeric ligand has been done on basis of elemental analysis, IR and 1HNMR. Thermal decomposition curve shows single decomposition step (305-530 0C). Thermal activation energy (Ea) calculated by Sharp-Wentworth (21.10 KJ/mole) method and Freeman-Carroll (21.46 KJ/mole) method are in good agreement. Freeman - Carroll and Sharp -Wentworth methods have been applied for the calculation of kinetic parameters while the data from the Freeman - Carroll methods have been used to determine various thermodynamic parameters.
