Synthesis and Characterization of Alkyd Resin Based on Soybean Oil Polyols

Abstract:

Soybean oil-based alkyd resin was prepared using soy-based polyol, maleic anhydride and phthalic anhydride. The soy-based polyol was obtained through the epoxidization of soybean oil, followed by ring-opening with methanol and, the hydroxyl values of soybean oil-based polyols used in this reaction is 169.93 mgKOH/g. In the reactions of soy-based polyol, maleic anhydride and phthalic anhydride, the molar ratio of hydroxyl value is equal to carboxyl value and the molar ratio of maleic anhydride to phthalic anhydride is 2:1, 1:1 and 1:2, respectively. 1% hydroquinone based on total reactants was used as inhibitor of polymerization, 1% dibutyltin oxide was used as catalyst.
