Reaction Steps

A polyglycidyl ether of a phenol formaldehyde condensate (a liquid epoxy novolac resin marketed by The Dow Chemical Company under the name DEN 438 (178 g; 1.0 equivalent), hydroquinone (0.07 g) and p-methoxyphenol (0.07 g) were combined in a 500 ml, 3-necked flask equipped with a mechanical stirrer, thermometer, dropping funnel and condenser. This epoxy resin was similarly reacted with thiodiethanol, acrylic acid and water in amounts and under conditions set forth in Experiment 1. Conversion was 72 percent complete after 80 minutes and 91 percent complete after 255 minutes at 80° C. The reaction was quenched after 255 minutes by cooling and additional water (45 g) added to adjust the solids level to 80 percent by weight.
