Embodiment 1
[0030] 1. Add 10.50g (0.005mol) hyperbranched polyester Boltorn H20 into the reaction vessel, heat it to a molten state, turn on the electric stirrer and condensing reflux device, add 0.04g hydroquinone, then add 2.88g (0.040mol ) acrylic acid and 11.00 g toluene.
[0031] 2. Control the temperature at 100°C. When the system forms a homogeneous solution, add 0.06g p-toluenesulfonic acid, reflux for 1 hour, and then cool in an ice-water bath.
[0032] 3. Dissolve the obtained product in 18.90g of N,N-dimethylformamide, add 0.30g of solid sodium hydroxide, and slowly add 6.06g (0.040mol) of glycidyltrimethylammonium chloride dropwise under constant stirring, The reaction was carried out at 50°C for 24 hours, and the solid sodium hydroxide was removed by suction filtration under reduced pressure.
[0033] 4. Remove and recover the solvent. Vacuumize to 0.10Mpa at 70°C and treat for 0.5 hours to remove and recover N,N-dimethylformamide to obtain modified hyperbranched polyester....
Embodiment 2
[0041] 1. Add 10.5g (0.005mol) of hyperbranched polyester into the reaction vessel, heat it to a molten state at 120°C, use an electric stirrer and a condensation reflux device, add 0.04g of hydroquinone, and then add 3.46g (0.048 mol) of acrylic acid and 13.00 g of toluene.
[0042] 2. Control the temperature at 105°C. When the system forms a homogeneous solution, add 0.08g p-toluenesulfonic acid, reflux for 1 hour, and then cool in an ice-water bath.
[0043] 3. Dissolve the obtained product in 19.00g N, N-dimethylformamide, add 0.20g solid sodium hydroxide, and slowly add 4.85g (0.032mol) glycidyltrimethylammonium chloride dropwise under constant stirring, React at 45°C for 24 hours. The solid was removed by suction filtration under reduced pressure.
[0044] 4. Remove and recover the solvent. Vacuumize to 0.10Mpa at 65°C and treat for 1 hour to remove and recover N,N-dimethylformamide to obtain modified hyperbranched polyester.
[0045] 5. Dissolve the modified hyperbr...
Embodiment 3
[0052] 1. Add 10.5g (0.005mol) of hyperbranched polyester into the reaction vessel, heat it to a molten state at 120°C, turn on the electric stirrer and the condensation reflux device, add 0.04g of hydroquinone, and then add 4.32g ( 0.060 mol) of acrylic acid and 13.00 g of toluene.
[0053] 2. Control the temperature at 110°C. When the system forms a homogeneous solution, add 0.08g p-toluenesulfonic acid, reflux for 1 hour, and then cool in an ice-water bath.
[0054] 3. Dissolve the obtained product in 18.80g of N,N-dimethylformamide, add 0.20g of solid sodium hydroxide, and slowly add 4.55g (0.030mol) of glycidyltrimethylammonium chloride dropwise under constant stirring, 50 ℃ should be 24 hours. The solid was removed by suction filtration under reduced pressure.
[0055] 4. Remove and recover the solvent. Vacuumize to 0.10Mpa at 70°C and treat for 0.5 hours to remove and recover N,N-dimethylformamide to obtain modified hyperbranched polyester.
[0056] 5. Dissolve the ...
