A number of resins have been prepared by the condensation of substituted benzoic acid with formaldehyde in the presence of different acids and bases as the catalyst. The intrinsic viscosity and Huggin's and Kraemer's constants of the resins were determined. The solubility behavior of the resins was studied. The IR spectra and the thermogravimetric analysis of the resins were also studied. The values of the energy of activation of degradation of the resins were computed by using the Freeman–Anderson method.
