Comparison of Thermal Degradation, WAXRD Studies and SEM of Renewable Resources Based Interpenetrating Polymer Networks

Recently bio-based polymers have received great importance due to their eco-friendly properties towards environment. As a substitute of conventional reinforcing synthetic polymer, bio-based polymers were from renewable resources like cardanol, i.e., the meta-substituted phenolic compound the chief product of CNSL. A number of IPNs have been synthesized by condensing di-azotised-4-amino benzoic acid and 3-amino benzoic acid cardanol dye with polyurethane of soybean oil. The IPNs produced have been characterized by FTIR, TGA, DSC (Differential scanning calorimetry). Elemental analysis and WAXRD studies. Thermal stability of IPNs has been studied by both TGA and DSC which provides heat capacity and kinetic parameters (order of reaction and activation energy) by Freeman Anderson method of the sample.
