Embodiment 1
[0023] Weigh 3 mol D4 into the reactor, add 0.3 mol sodium hydroxide, stir at 60°C for 1 hour, then add 0.3 mol deionized water, 0.1 mol ethylenediamine, keep the temperature at 60°C, and continue stirring for 6 hours , to obtain a viscous transparent liquid. The product was washed with deionized water until neutral, and the monomer was removed by vacuum to obtain the product.
Embodiment 2
[0025] Weigh 3 mol D4 into the reactor, add 0.25 mol sodium hydroxide, stir at 80°C for 0.5 hours, then add 0.05 mol deionized water, 0.8 mol 3,3'-diaminodipropylamine, keep the temperature The temperature was 80°C, and the stirring was continued for 5 hours to obtain a viscous transparent liquid. The product was washed with deionized water until neutral, and the monomer was removed by vacuum to obtain the product.
Embodiment 3
[0027] Weigh 3 mol D3 into the reactor, add 0.1 mol sodium hydroxide, stir at 40°C for 2 hours, then add 0.012 mol deionized water, 0.2 mol ethylenediamine, keep the temperature at 40°C, and continue stirring for 4 hours , to obtain a viscous transparent liquid. The product was washed with deionized water until neutral, and the monomer was removed by vacuum to obtain the product.
