Diethyl Ether → 2-Ethoxyethyl methacrylate

To a solution of 20 g methacrylic acid in 50 ml dichloromethane was added 19 g ethyl vinyl ether in 30 ml dichloromethane. The mixture was stirred overnight at room temperature and poured into ether and washed with a saturated aqueous solution of sodium bicarbonate until the solution ceased effervescing. The organic layer was dried with MgO/MgSO4 and concentrated in vacuo. The residue was distilled at 25° C./0.1 torr to give 7.1 g (19% yield) of ethoxyethyl methacrylate. A mixture of 7.0 g ethoxyethyl methacrylate and 0.076 g AIBN in 7 ml MEK was heated to 60° C. for 24 hr and 7 ml MEK was added. This solution (solution E) was used for further evaluation.
