TECHNOLOGY FOCUS - POLYMERS - Preparation: No general preparation is given. EXAMPLE - 4-Hydroxy butylacrylate (in g) (50) and triethylamine (38.6) were added to tetrahydrofuran (430 ml), and stirred. Then, methanesulfonyl chloride (40.9) was dripped to the resulting solution and stirred at room temperature for 2 hours, and water (500 ml) was added. The resulting mixture was extracted using ethylacetate, and the extract was dried using saturated salt solution and anhydrous sodium sulfate, to obtain a methanesulfonyl compound (A). Cyanuric chloride (2.68) and potassium carbonate (6.63) were added to N,N-dimethylacetamide (50 ml). Then, 4,4'-dimethoxy diphenylamine (10) was added to the resulting solution and stirred at 80 degrees C for 2 hours, and water (100 ml) and ethylacetate (100 ml) were added. The resulting mixture was dried using saturated salt solution an anhydrous and magnesium carbonate and purified using hexane and ethylacetate with silica gel chromatography, to obtain triazine intermediate compound (I) (4.57). The obtained triazine intermediate compound (I) (4.7) was added to dichloromethane (30 ml) and stirred at 78 degrees C. Then, boron tribromide chloroform solution (39.5 ml) was dripped to the resulting solution and stirred at 0 degrees C for 1 hour. Water (50 ml) was dripped to the resulting solution and stirred for 30 minutes. The resulting mixture was extracted and dried, and the solid product was washed using water and acetone to obtain a triazine intermediate compound (II) (1.30). The obtained triazine intermediate compound (II) (1.30), methanesulfonyl compound (A) (3.82) and potassium carbonate (2.38) were added to N,N-dimethylacetamide (20 ml) and stirred at 80 degrees C for 7 hours. Then, water was added to the resulting solution, extracted using ethylacetate, dried using saturated salt solution and anhydrous magnesium carbonate under reduced pressure and purified using hexane and ethylacetate with silica gel chromatography, to obtain a triazine-containing polymeric compound (1.17) of formula (1A).
