The present invention provides a method for manufacturing palm oil based polyols or diols having a moderate molecular weight of between 800 and 3000 and a desired hydroxyl content of between 2 and 4 that make it suitable for use as starting material in making polyurethane based materials that include adhesives and coatings. The palm oil based polyols or diols are made by way of acrylation or methacrylation using acrylic acids or methacrylic acids or any other modified product of acrylic acid with the addition of inhibitor and catalyst under appropriate conditions, hydroxylation of palm olein based oleic acid by way of direct partial esterification using glycerol with the addition of catalyst and solvent, hydroxylation of palm olein by way of removing double bonds in said palm olein structure using hydrogen peroxide in solvent with the addition of catalyst and/or hydroxylation of palm olein by way of oxidization using a hydrogen peroxide-tungstic acid system.
