Procedure
0.02 g of 2,6-di-tert-butyl-4-methylphenol, 0.01 g of Desmorapid Z, 13.3 g of 4-(methylthio)phenyl isocyanate in 25 g of ethyl acetate were initially introduced into a 100 ml round-bottomed flask and heated to 60° C. Thereafter, 11.6 g of 3-hydroxybutyl acrylate were added dropwise and the mixture was kept further at 60° C. until the isocyanate content had fallen below 0.1%. Thereafter, the ethyl acetate was distilled off at 5 mbar and cooling was effected. The product was obtained as a crystalline solid.
