Reaction Steps

1,2-Epoxy-3-phenoxy propane (150 g; 1.0 equivalent), hydroquinone (0.06 g) and p-methoxyphenol (0.06 g) were combined in a reaction vessel detailed in Experiment 4. The flask and contents were heated to 80° C. and a solution of thiodiethanol (24.4 g; 0.2 equivalent), acrylic acid (72 g; 1.0 equivalent), and water (18 g) was added dropwise over a 25-minute period with stirring. A reaction temperature was similarly maintained at 80° C. and conversion followed by acid consumption. The conversion was 66 percent complete at 45 minutes, 86 percent complete at 170 minutes and 88 percent complete at 390 minutes at which time the reaction was quenched. Additional water (9.0 g) was added to adjust the solids level to 90 weight percent.
