  • Vinyl-containing compounds and processes for making the same
    Patent number: 10570107
    Abstract: The present invention provides a process for forming vinyl-containing compounds including the steps of: a) reacting in a nitrogen atmosphere a dicarboxylic acid and/or anhydride and a functional mono or polyfunctional alcohol 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 azeotropic agent; and c) reacting the vinyl functional esterified intermediate, residual esterification catalyst and residual vinyl-containing organic acid with an epoxy to provide the vinyl-containing compound.
