Procedure

10.2 g of 2,4-dimorpholino-6-(4-hydroxy-2,2,6,6-tetramethylpiperidin-1-yl)-1,3,5-triazine (product from Example 34) are heated to 120° together with 6.9 ml of ethyl methacrylate, 0.04 g of 2,6-bis-tert-butyl-p-cresol and 0.04 ml of tetrabutylorthotitanate (monomer), some liquid slowly being removed by distillation. The mixture is allowed to react for 50 hours, some ethyl methacrylate and catalyst subsequently being added periodically. After the reaction has ended, the product is filtered through bleaching earth and evaporated. The residue is dissolved in toluene/acetone and purified chromatographically on an SiO2 column, the above product being obtained as a colorless resin.
