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.
Claims10
A process for forming vinyl-containing compounds, the process comprising the steps of:
- a) reacting in an inert 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 azeotropic agent while in the inert 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 inert 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.
