Oxalyl chloride (130 g; 1.02 mol) was charged in a reactor, and a warm solution of acrylamide (71 g; 1.0 mol) in dichloroethane (250 ml) was dropwise added thereto (reaction temperature, 10° to 30° C.). After completion of the dropwise addition, the solvent and excess of the oxalyl chloride were removed by distillation under reduced pressure to obtain 2-vinyloxazoline-4,5-dione hydrochloride (161 g) as a yellow oil. Viscosity, 100,000 cp.
