This ?-ketoester was used to make a simple coatings mixture, which was, in turn, used to coat metal panels. Crosslinking was attempted using multifunctional amines, but this proved to be too rapid for any reasonable films to be made. Michael addition with multifunctional acrylates proved to be controllable by adjusting the catalyst level. The films obtained proved to have high levels of solvent resistance, high hardness, good gloss, and low impact strength. Gel content measurements and large increases in the glass transition temperature (T g) of the cured films indicated that high levels of crosslinking have been obtained.

ThermodurcissablesIndex. décimale : 667.9 Revêtements et enduits Résumé : An oxazoline with an unsaturated side chain was reacted with m-chloroperbenzoic acid in order to convert the unsaturation to oxirane moieties. 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.

ThermodurcissablesIndex. décimale : 667.9 Revêtements et enduits Résumé : The side chain double bonds of poly(decenyloxazoline) were epoxidized using standard techniques. The epoxidation was facile and a high percentage of the double bonds were converted to oxirane groups. Films of the epoxidized resin were cured at an elevated temperature with either diamine or anhydride crosslinking agents. Both types of crosslinking agents yielded cured films with good solvent resistance, high hardness, and high gloss. The films cured with the anhydride crosslinkers and the higher molecular weight diamine had better properties than the films cured with the low molecular weight diamine. This could be because some of the low molecular weight diamine was lost due to evaporation during the cure cycle, which would result in lower crosslink density.

Revêtements en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Low molecular weight resins containing relatively high levels of acrylic acid were converted to oxidatively curable materials by reacting the carboxylic acid groups with oxazoline functional alkenes. The oxazolines were obtained by reacting fatty acid with 2-amino-2-methyl-1-propanol. The oxazolines were then reacted with the acrylic resins at elevated temperature. Relatively high yields of the desired reaction products were obtained in relatively short reaction times. The resulting resins were formulated into aqueous coatings and films were made over metal substrates. The films were cured oxidatively and evaluated for property development. The films had good general solvent resistance but poor resistance to dilute sodium hydroxide.

Analysis of the acetoacetylated material via NMR and elemental analysis showed that 60–80% of the available reactive moieties of shellac had been converted to ester. Crosslinked films were produced by reacting the acetoacetylated shellac with a multifunctional amine or with a multifunctional acrylate under Michael addition conditions. The films had good properties in terms of solvent resistance, hardness, and gloss, but proved to be somewhat brittle.
