The conversion of double bonds to oxirane is high provided a significant excess of the perbenzoic acid is used. The conversion was monitored using NMR spectroscopy. The unsaturated oxazoline was reacted with an acid-functional acrylic, and the resulting adduct was reacted with m-chloroperbenzoic acid to epoxidize the pendent unsaturation. Again, a significant excess of the peracid was required to reach high conversion of the double bonds. The epoxidized oxazoline and the modified acrylic were evaluated in thermoset coatings over metal panels. The properties of the films ranged from moderate to good depending on what species was used as a crosslinker.
