Abstract

---

Alkyd resin was prepared from shear butter oil (SBO) using the two step procedures; alcoholysis and polyesterification. The oil and alkyd resin were characterized and evaluated by standard methods, for their physico-chemical properties. The analysis showed that the alkyd resin based on Shea butter oil recorded average acid value of 15.2 (mgNaOH/g), iodine value (98.0 mg/g), PH value 6.7, density 1.36 g/cm3 , formaldehyde value of 0.05 ppm, saponification value 842.0 mgKOH/g, and Drying time 6000 seconds. The FT-IR studies showed that, the ester formation is indicated by C = O band at 1723 cm-1 and C – O band at 1201 cm-1 , and the aromatic C = C double bond at 1617 cm-1 band.
