Notizen: Abstract Acrylates and methacrylates of 1,3(2,4-dihydroxyphenyl)-di(2H-benzotriazole) and 1,3(2,4,6-trihydroxyphenyl)-di(2H-benzotriazole) have been prepared by treating acrylic acid or methacrylic acid with N,N′-dicyclohexyl carbodiimide and then allowing this mixture to react with the phenolic ultraviolet absorbers to give 1,3[2-hydroxy-4-acryloxy(methacryloxy)phenyl]-di(2H-benzotriazole) and 1,3[2,6-dihydroxy-4-acryloxy(methacryloxy)phenyl]-di(2H-benzotriazole). The yield of the esters was from 10 to 30%; they were characterized by their infrared, 1H, and 13C NMR spectra; their polymerizability was demonstrated. The compounds had X of 330 to 335 nm with extinction coefficients ranging from 3.0 to 3.5×104 L/mol·cm.
