Abstract

Cardanol(Cashew phenol) is subjected to diazotisation with Aniline and m-Toluidine to get monomers like Cardanol based dye from Aniline (CBDFA) and Cardanol based dye from m-Toludine (CBDFT). Such monomers have been condensed with formaldehyde in presence of acid catalyst to form resins. The resins have been characterized by FTIR spectra and their thermal behaviour have been studied.DOI: http://dx.doi.org/10.3126/ijasbt.v2i2.10544Int J Appl Sci Biotechnol, Vol. 2(2): 176-179

Highlights

Renewable sources as a substitute to petrochemical derivatives have attracted the attention of many researchers for the synthesis of polymers
Cardanol based polymers have wide applications in composites (Tan, 1997; Sathiyalekshmi, 1993), polyurethanes (Sathiyalekshmi and Gopalakrishnan, 2000; Mythili et al, 2004; Das and Lenka, 2011; Athawale and Shetty, 2010), surface coating (Santeusanio et al, 2013) and few others (Unikrishnan and Thachil, 2006; Unikrishnan and Thachil, 2008; Devi and Srivastava, 2006; Devi and Srivastava, 2007). This communication reports on the synthesis, characterization and thermal analysis of resins obtained by condensation of cardanol-based dyes with formaldehyde
FTIR Spectra Fourier transform infrared (FTIR) spectra of Resin- 1 and Resin -2 are shown in Fig. 1(a) and 1(b) respectively
