This invention relates to a process for obtaining highly pure aliphatic dialkyl esters of saturated dicarboxylic acids from vegetable oils, which can advantageously be used in polymerization. The process comprises the steps of reacting with an aliphatic alcohol a triglycerides mixture containing at least one triglyceride of at least one saturated dicarboxylic acid in the presence of one or more catalysts capable of catalyzing the esterification and transesterification reactions, and separating the dialkyl esters of saturated dicarboxylic acids from the reaction mixture thus obtained.

This invention relates to bio-based polyfunctional carboxylic acids reacted with vinyl ether compounds to form liquid vinyl-blocked bio-based polyfunctional carboxylic acids. These liquid vinyl-blocked bio-based polyfunctional carboxylic acids can be mixed with a polyfunctional vegetable oil-based epoxy resin to form a homogeneous curable coating composition. Upon curing at elevated temperature, thermoset coatings are formed which have excellent hardness, solvent resistance, adhesion, and flexibility. The invention also relates to the use of a curable coating composition comprising at least one polyfunctional vegetable oil-based epoxy resin and at least one vinyl-blocked bio-based polyfunctional carboxylic acid, which may be coated onto a substrate and cured thermally. Methods of making the vinyl-blocked bio-based polyfunctional carboxylic acids and curable coating compositions and substrates containing the same are also disclosed.
