Procedure

A distillation line was installed instead of the condenser and the obtained tri-n-butyl(2-hydroxyethyl)phosphonium chloride was dissolved in 500 ml of acetonitrile. The solution was heated under a normal pressure while stirring and about 200 ml of acetonitrile was distilled. A condenser having a calcium chloride tube was installed, 1.5 g of hydroquinone monomethyl ether was added as a polymerization inhibitor, and 85.9 g (0.822 mol) of methacryloyl chloride was added thereto dropwise at 50° C. over 2 hours through a dropping funnel, then the solution was maturated for 3 hours at the same temperature.
