| 摘要 |
<p>This invention is directed to thermosettable ethylenically unsaturated epoxy ester resin compositions having improved storage stability and to a method for improving the storage stability of such compositions by adding an anaerobically effective polymerization inhibitor to the resin composition. The resin composition comprises the reaction product of a bisphenol-base epoxy resin, a novolac-base epoxy resin, or a mixture thereof with an ethylenically unsaturated monocarboxylic acid dissolved in a polymerizable monomer containing a > C=CH<Sub>2</Sub> group. The polymerization inhibitors of this invention are 4-chloro-2-nitrophenol, 2,4-di- chloro-6-nitrophenol, or mixtures thereof.</p> |
