The terpolymer resin p-hydroxyacetophenone- quinhydrone –melamine(abbreviated as PAQM-I) was synthesized by the condensation of p-hydroxyacetophenone (0.1M), quinhydrone (0.1M) and melamine (0.1M) in the presence of polyphosphoric acid (PPA). The structure of resin was determined by its elemental analysis, UV-VIS, IR and NMR data. The molecular weight of terpolymer was determined by non-aqueous conductometric titration technique. Thermo kinetic parameter was determined by Freeman- Carroll (FC) and Sharp-Wentworth (SW) method. The order of degradation reaction determined by FC method was confirmed by SW method.
