In this study, the avocado seed oil contents were synthesised according to the alcoholysis-polyesterification process and the fatty acid profile of the raw oil was evaluated using GC-MS while structural elucidation of the raw avocado seed oil (ASO), desaturated ASO and ASO based resin were evaluated using FTIR. The physio-chemical properties of crude Avocado seed modified oil showed that the neutralization process reduced the FFA content of crude oil from 1.85 to 1, with a refractive index of 1.461 from 1.441, acid value increases from 3.92 to 6.28 mg KOH/g, saponification value varied from 38.23 to 143.61. The iodine value showed an astronomical increase from 39.3 g I2/100g to 125.5 g I2/100g. Results obtained show that the polyester- based ASO has high drying speed in presence of drying agent. It exhibited excellent adhesion and abrasion qualites and can be used for alkyd resin synthesis.
