Jatropha seed oil was employed in the preparation of different alkyd resin samples using alcoholysis and polycondensation process. The alkyds formation was monitored by determining the acid number of the reaction mixture at time intervals and the extents of the polyesterification reactions were evaluated. Both the Jatropha seed oil and its alkyd resins were characterized by Fourier Transform Infra red (FTIR) spectroscopy. Performance evaluation shows that properties of alkyd resin derived from Malic anhydride are comparable with pthalic anhydride alkyd resins. However the Maleic alkyd resin shows better color, and lower poly condensation time. Better results were observed from the blending of pthalic and small portions of maleic anhydride.
