Abstract

The resin (abbreviated as PNPRF-II) was derived from acid catalyzed polycondensation of p-nitrophenol (0.2M), resorcinol (0.1M) and formaldehyde (0.4M) using 1M HCl at 120-125°C. The tentative structure of this resin was determined by elemental analysis, 1H NMR, FT-IR and UV-Vis spectra. The molecular weight was determined by non-aqueous conductometric titration. The thermokinetic parameters were determined using Freeman-Carroll (FC) and Sharp Wentworth (SW) method in temperature range (217-502°C).The values of activation energies (Ea), entropy (ΔS) and free energies (ΔG) obtained by both method. The order of degradation reaction determined by FC method was confirmed by SW method.
