Reaction Steps
A diglycidyl ether of a polypropylene glycol (a liquid epoxy resin marketed by The Dow Chemical Company under the name DER 736) having an epoxy equivalent weight of about 190 (190 g; 1.0 equivalent), hydroquinone (0.07 g) and p-methoxyphenol (0.07 g) were combined in a reaction vessel equipped as set forth in Experiment 1. This epoxy resin was similarly reacted with thiodiethanol, acrylic acid and water in amounts and under conditions set forth in Experiment 1. The conversion was 95 percent complete at 70 minutes and 100 percent complete at 80 minutes of reaction time. The final reaction product was 92 percent solids and water and had a Gardner viscosity of U. This reaction product was easily diluted with water in amounts up to about 35 weight percent water before phase separation occurs.
