Participants

Reaction Steps

The resin of this example was prepared in the presence of 5 percent water based on total solids, and had a water-to-amine nitrogen (of the amine acid salt) equivalency of 1.74:0.44. A dimethyl ethanolamine lactate was prepared by admixing 13.3 parts of dimethyl ethanolamine and 18.0 parts of lactic acid (85 percent solution in water). The mixture was held at 40°C. to 60°C. for a short time and there was then added 7.2 parts of isopropanol. The final composition consisted of 75 percent solids and contained 7.1 percent water.
