Abstract
Cardanol, the major constituent of cashew nut shell liquid (CNSL), is extracted from CNSL by vacuum distillation at 3–4 mm pressure of mercury and 230–240°C temperature. Cardanyl acrylate, a derivative of cardanol, is prepared by the Kaliyappan method. A number of resins have been synthesized by condensing cardanyl acrylate with furfural and selective organic compounds in the presence of acid as catalyst. The resins have been characterized by Fourier transform infrared spectra. Solvent absorptivity of the resins have been studied by taking toluene and dimethyl formamide as solvents. The thermal behavior of the resins have been studied. The overall activation energy and order of degradation of the resins have also been evaluated using the Freeman-Anderson method.
