Procedure

A mixture of 22.0 g (35.0 mmoles) of 2-phenyl-4-(2-hydroxy-4-n-hexyloxy-phenyl)-6-[2-hydroxy-4-(11-hydroxy-undecyloxy)phenyl]-1,3,5-triazine, 4.4 g (42.0 mmoles) of methacryloyl chloride (Fluka, 97% ), 0.5 g (6.3 mmoles) of pyridine in 100 mL of toluene (Merck, 99.5%) are heated at 80°-85° C. for 21 hours. After cooling to 55° C., there are added 8.9 g (87.5 mmoles) of triethylamine (Fluka, 99.5%). The mixture is heated at 80° C. for further 7 hours then filtered hot. The filtrate is evaporated. The crude product (25.7 g ) is dissolved in 120 mL of CH2Cl2, filtered through a Kieselgel 60 pad (230-400 mesh; 6.5 cm diameter; h=5 cm) and eluted with 380 mL of CH2Cl2. Solvent removal and drying at 80° C./0.1 mmHg for 2 hours 30 min. give 22.3 g (91.4% yield ) of 2-phenyl-4-(2-hydroxy-4-hexyloxyphenyl)-6-[2-hydroxy-4-(11-methacryloyloxy-undecyloxy)-phenyl]-1,3,5-triazine, as an orange resin, Tg=-13° C. (DSC).
