Reaction Steps

A mixture of 39.5 g (0.095 mol) of 2-mesityl-4,6-bis(2,4-dihydroxyphenyl)-1,3,5-triazine (compound 1b), 40.7 g (0.2185 mol) of 2-ethylhexyl glycidyl ether (purity 98%) and 3.5 g (9.5 mmol) of ethyltriphenylphosphonium bromide (purity 97%) in 250 ml of mesitylene (purity 99%) is stirred at 140° C. under nitrogen for 16 hours. The clear solution is freed from solvent under reduced pressure. The crude product is dissolved in 200 ml of ethyl acetate and filtered through a 6.0 cm layer of silica gel 60 (230-400 mesh) of diameter 8.0 cm, with elution with 1000 ml of ethyl acetate. Removal of the solvent and drying for 2 hours at 100° C. and a pressure of 0.6 mmHg (80 Pa) give 61.3 g (yield 81.8%) of the title product (compound 7; Tg 54.4° C.) of the formula ##STR106## where R=CH2 --CH(OH)--CH2O--CH2 --CH(C2 H5)--CH2CH2CH2CH3.
