実験手順

0.015 g of 2,6-di-tert.-butyl4-methylphenol, 0.007 g of Desmorapid Z, 9.4 g of 3-bromophenyl isocyanate were initially introduced in a 20 ml sample bottle and heated to 60° C. Thereafter, 5.5 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%. Cooling was then effected. The product was obtained as a crystalline solid.
