Preparation and characterization of polyvinyl oleate by esterification reaction between polyvinyl alcohol and oleic acid

Polyvinyl Oleate was prepared by esterification reaction between Polyvinyl Alcohol and Oleic Acid catalyzed by sulfuric acid and also in the absence of it. The reactant concentration was varied as 1 : 1 mol and 1 : 2 mol regarding to oleic acid in 2.5 hours of reaction. The formation of the ester was confirmed by FTIR and HNMR. FTIR spectra showed the wavenumber as 1100-1200 cm−1 assigned to C-O-C functional group. HNMR chemical shift showed the signal at δH 4.7 ppm and δH 4.9 ppm were attributed to vinyl ester proton. The decrease of acid value of the product indicated that esterification reaction has been proceeded, with the highest conversion as 97.4%.
