The furan resins have been synthesized by condensation of furfuryl alcohol with anisaldehyde/salicyldehyde and furfuraldchyde with furfuryl alcohoVp-cresol using acid or base or metal salt as catalyst. These resins have been characterized by Fourier Transform Infra-red spectra (FTIR) and cross-linking of these resins arc accomplished by using various curing agents. These resins find extensive application in spandex fibers, laminates, lining for rocket fuels, abrasive wheels etc.
