Versuchsvorschrift

To a reaction vessel fitted with an air-bleed tube, thermometer, stirrer, and condenser there are charged sulfopropionic anhydride (29.1 g.), 2-hydroxypropyl methacrylate (29.1 g.), the monomethyl ether of hydroquinone (0.1 g.) and toluene (60 g.). The mixture is stirred, sparged with dry air as in (1) above and heated. After 0.5 hour at 60° C. a solution containing 29% by weight of methacryloxyisopropyl sulfopropionate is obtained.
