Procedure

Itaconic acid (18.5 g; 0.142 mol) and methylamine (41% in water, 10.7 g based on the aqueous solution, 0.142 mol, 1.0 equivalent) were mixed as in example 8. In addition, the addition of 20 ml of water was required in order to prevent formation of precipitate at 50° C. NMR analysis showed that the itaconic acid:4-carboxy-1-methylpyrrolidone ratio was 100:0.
