Vinyl-containing compounds and processes for making the same

A process for forming vinyl-containing compounds, the process comprising the steps of:

• a) reacting in a nitrogen atmosphere at least one dicarboxylic acid and/or anhydride and a monofunctional or polyfunctional alcohol to an endpoint of an acid number of 10 or less to provide a hydroxyl-containing polyester;
• b) reacting the hydroxyl-containing polyester with a vinyl-containing organic acid in the presence of an esterification catalyst, a polymerization inhibitor and an zeotropic agent while in the nitrogen atmosphere to provide a vinyl functional esterified intermediate group;
• and
• c) reacting the vinyl functional esterified intermediate, residual esterification catalyst and residual vinyl-containing organic acid with an epoxy while in the nitrogen atmosphere to provide the vinyl-containing compound wherein the nitrogen atmosphere in steps a)-c) is devoid of oxygen and the reactions are under inert conditions.
