Abstract
This research paper deals with the synthesis and characterization of resins from renewable source cardanol. p-Anisidine has been diazotised and coupled with cardanol to prepare diazotised p-anisidine cardanol dye. The dye obtained has been condensed with formaldehyde in presence of hydrochloric acid to give diazotized p-anisidine cardanol formaldehyde resin. The condensed product has been allowed to react with organic compounds such as o-amino benzoic acid, resorcinol and thiourea to form various resins. The resins were characterized by UV and FT-IR, 1H-NMR spectroscopy. The thermal behavior of the resins has also been studied using thermo gravimetric analysis (TGA) and differential thermal analysis (DTA).
