Versuchsvorschrift

In a separate vessel, succinic anhydride (30 g), 2-hydroxyethyl acrylate (34.2 g), tetramethylammonium chloride (0.2 g), and 2,6-di-t-butyl-4-methylphenol (0.15 g) were stirred and heated at 90° C. for 3 hours. The mixture was then cooled to give 3-(2-acryloyloxyethoxycarbonyl)propionic acid. This product (27.2 g) was mixed with 2,6-di-t-butyl-4-methylphenol (0.1 g) and added over 1 hour to the advanced resin at 100° C. The mixture was then stirred for a further 41/2 hours at 100° C., by with time its epoxide content had fallen to a negligibly low level.
