1. Add secondary amine and excess chloropropene to the reaction kettle, and add a catalyst amount of sodium hydroxide. Raise the temperature to 120 ℃, react for a period of time at 0.15~0.2MPa, automatically raise the temperature to 210~230 ℃, pressure 4.5~8.5MPa, and react for 3~4 hours. Obtaining quaternization products. Cool and depressurize, transfer the material into a distillation kettle to evaporate excess chloropropene. Then, steam out the quaternized product under reduced pressure.
2. Add the above products to the polymerization kettle, dissolve them with water, replace the air in the kettle with nitrogen, start heating up, add peroxide initiator, and react at 80-90 ℃ for 4 hours to obtain the polymer.
Add secondary amine and excess chloropropene to the reaction kettle, and add the catalyst amount of sodium hydroxide. The temperature is raised to 120 ℃, the reaction is carried out at 0.15~0.2 MPa for a period of time, the temperature is automatically raised to 210~230 ℃, the pressure is 4.5~8.5 MPa, and the reaction is carried out for 3~4 h. Quaternized products. Cooling and reducing the pressure, moving the material into the distillation kettle, and evaporating excess chloropropene. The quaternized product is then steamed under reduced pressure.
After the above products are added to the polymerization kettle, water is added to dissolve the air in the kettle with nitrogen, the temperature is increased and a peroxide initiator is added, and the polymer is reacted at 80~90 ℃ for 4 h.
