Procedure: A mixture of 2-dodecylsuccinic anhydride (42.17 g, 147.4 mmol), 3-(3,5-di-t-butyl-4-hydroxyphenyl)propanoic acid hydrazide (43.31 g, 147.4 mmol) and 70 ml of toluene was refluxed for one hour under a nitrogen atmosphere with the azeotropic removal of water (Dean-Stark assembly). The bulk of the solvent was distilled off followed by vacuum stripping of the hot (160° C.) melt for about 10 minutes. The resulting yellow liquid was then cooled under vacuum to about 120° C. The vacuum was released and the melt was quickly poured into a container. Upon cooling, the liquid became a clear yellow glass. The product was recrystallized from acetone/water at ice bath temperatures to afford, after drying, a nearly quantitative recovery of the product as a white powder having a melting range of 55°-60° C. The bulk of the solvent was distilled off the melt was quickly poured into a container Upon cooling The product was recrystallized from acetone/water at ice bath temperatures to afford after drying

Procedure: The procedure of Example 75 is repeated using 1-heptyloxy-4-amino-2,2,6,6-tetramethylpiperidine and n-dodecyl succinic anhydride to afford the title compound.

Procedure: A reaction vessel containing 53.5 parts of Polyepoxide A (80 percent solids in isophorone) was heated to 70°C. There were added 3 parts of an amine produced by reacting dimethylethanolamine with dodecylsuccinic anhydride, and then there were added 6 parts of a second amine produced from dimethylethanolamine and maleic anhydride. During the second addition the temperature was raised to 95°C. and stirring was continued for 15 minutes at this temperature. The product when diluted with water and electrodeposited, as in the above examples, provided an adherent solvent-resistant coating. produced
