Reaction Steps

The 4'-[N-methyl-N-(11-hydroxyundecyl)-amino]-4-nitroazobenzene obtained in process step 1 was reacted with methacryloyl chloride according to the method stated in Example 2, Section 2, to give 4-nitro-4'-[N-methyl-N-(11-methacryloyloxyundec-1-yl)-amino]-azobenzene [methacrylate (A)]. The resulting product had the following physicochemical properties: IR spectrum (KBr pellet): bands at 2,900, 2,850, 1,705, 1,585, 1,490, 1,325, 1,120, 1,150, 1,095, 850 and 810 cm-1 ; 1H nuclear magnetic resonance spectrum (400 MHz, CDCl3, tetramethylsilane as internal standard, chemical shift δ (in ppm): 1.3 to 1.65 (multiplet, 18H), 1.9 (singlet, 3H), 3.1 (singlet, 3H), 3.4 (triplet, 2H), 4.3 (triplet, 2H), 5.6 (singlet, 1H), 6.1 (singlet, 1H), 6.7 (doublet, 2H), 7.9 (doublet, 4H), 8.3 (doublet, 2H); elemental analysis: calculated: 67.3% C, 8.03% H, 13.13% N, 11.25% 0; found: 66.1% C, 7.7% H, 13.8% N, 12.1% 0.
