Determination of Thermal and Dielectric Properties of linear p-substituted Phenol with Methylene Bridge

Present study highlights the thermal analysis from TG thermogram to obtain the activation energy, structural analysis and effect of p- substituted groups on dielectric constant/loss. A novel method is used for the preparation of new linear polymer from p- substituted phenol with Methylene Bridge like –Cl, -COOH, -NO2 etc. and these polymers have been characterized by IR, NMR and TGA method. Thermal degradation at different temperatures with mass loss in percentage, calculate. There otically mass loss, thermal stability, we have studied the structure analysis from TGA with respect to mass loss at different temperatures. These polymers possessed high molecular weight low proportion of unreached methylene groups. With these sample of polymers were characterisation by TGA method excellently.
