Reaction Conditions

Temperature	60 °C

Reaction Steps

0.25 g of 2,6-di-tert-butyl-4-methylphenol, 0.12 g of Desmorapid Z, 126.4 g of phenyl isocyanate were initially introduced into a 500 ml round-bottomed flask and heated to 60° C. Thereafter, 123.3 g of 2-hydroxyethyl acrylate were added dropwise and the mixture was kept further at 60° C. until the isocyanate content had fallen below 0.1%. Cooling was then effected. The product was obtained as a crystalline solid (preparation described in DE 2329142).
