2- 2-Hydroxy-4-alkoxy- 2-oxypropyl

Instead of acryloyl chloride or methacryloyl chloride, the glycidyl esters are used for functionalization with polymerizable compounds. Such a compound is 2-[2-hydroxy-4-alkoxy-(2-oxypropyl methacrylate)phenyl]-2H-4-methoxybenzotriazoIe, as shown in Figure 9.9. It is prepared by the reaction of 4-(5-methoxy-2H-benzotriazole-2-yl)resorcinol with glycidyl methacrylate. Tetrabutylammonium bromide is used as a catalyst and hy-droquinone is used as a polymerization inhibitor.
