| 摘要 |
The present invention provides an improved process for reducing the premature gelation during esterification of epoxy compounds containing tertiary, allylic or benzylic hydrogens (e.g., saturated epoxy resins) with ethylenically unsaturated monocarboxylic acids (e.g., acrylic acid) wherein the epoxy compound in pre-reacted with a trialkylphosphite (e.g., triethylphosphite) prior to the esterification.
