Embodiment 1
[0138] Example 1: Synthesis of Polymer 1
[0139] 38.21 g (0.1 mol) of bisaminophenol 1 was dissolved in 300 ml of distilled N-methyl-pyrrolidone (NMP), and 23.93 g (0.095 mol) of diaminophenol was added dropwise to the solution at 10°C with stirring. A solution of formyl chloride 1 in 200 ml of distilled NMP. Stir at 10°C for one hour and then at 20°C for one hour, then cool to 10°C, add 1.64 g (0.01 mol) of capped 3 (dissolved in 50 ml of distilled γ- Butyrolactone (γ-BL)) and stirred at 10°C for one hour, then at 20°C for one hour, the reaction mixture was cooled to 10°C, and 19.76 g (0.25 mol) of pyridine (dissolved in 30 mL of distilled γ-BL) and the reaction mixture was warmed to room temperature and stirred for 2 hours.
[0140] In order to isolate the polymer, the reaction mixture was filtered and the filtrate was added dropwise to a mixture of 1 liter of demineralized water and 200 milliliters of isopropanol with stirring, and 3 liters of demineralized water were ad...
Embodiment 2
[0142] Example 2: Synthesis of Polymer 2
[0143] 36.3 grams (0.095 moles) of bisaminophenol 1 were dissolved in 300 milliliters of distilled NMP, and 27.8 grams (0.1 moles) of diformyl chloride 2 was added dropwise to the solution in 250 milliliters of distilled NMP at 10°C with stirring. A solution of γ-BL. Stirred at 10°C for one hour and then at 20°C for one hour, and after cooling to 10°C, 80 g (0.02 mole) of bismuth dissolved in 200 ml of distilled γ-BL was added dropwise to the reaction mixture. Aminophenol compound 1 was stirred for one hour at 10°C and then stirred for one hour at 20°C. The reaction mixture was cooled to 10°C and 25.28 g ( 0.25 mol) triethylamine (TEA) and the reaction mixture was warmed to room temperature and stirred for 2 hours.
[0144] To isolate the polymer, the reaction mixture was filtered and the filtrate was added dropwise with stirring to cyclohexane or a mixture of 4 liters of cyclohexane and 2 liters of demineralized water and stirred a...
Embodiment 3
[0146] Example 3: Synthesis of Polymer 3
[0147] 28.31 grams (0.05 moles) of bisaminophenol 2 were dissolved in 250 milliliters of distilled NMP, at 10° C. under stirring, 8.82 grams (0.03 moles) of diformyl chloride 3 and 3.53 grams ( 0.0175 mol) of diformyl chloride 4 in 150 ml of distilled γ-BL solution. After stirring at 10°C for one hour and then at 20°C for one hour, and cooling to 10°C, 0.52 g (0.005 mol) of capped 1 dissolved in 20 ml of distilled γ-BL was added dropwise to the The reaction mixture was stirred at 10° C. for one hour and then at 20° C. for one hour. The reaction mixture was cooled to 10° C., and 9.48 g (0.12 mol ) pyridine and the reaction mixture was warmed to room temperature and stirred for 2 hours.
[0148] The isolation and workup of polymer 3 was carried out in a similar manner to Example 1.
