Method and device for continuously preparing anion resin based on polyoxyxylene

The invention belongs to the field of high polymer chemistry, and discloses a method and device for preparing anion resin based on polyoxyxylene, polyoxyxylene and a solvent are added into a bromination reaction kettle to be dissolved, bromine is dropwise added, and brominated polyoxyxylene feed liquid is obtained after reaction; feeding the brominated polyoxyxylene feed liquid and an aminating agent into an amination reaction kettle for reaction to obtain anion resin feed liquid; and outputting the anion resin feed liquid to a drying machine, drying to obtain the solid polyoxyxylyl anion resin, and recovering the solvent. According to the method and the device for preparing the anion resin based on the polyoxyxylene, the solvent can be recycled in the production process, so that the production process is simplified, the production cost is reduced, the emission of organic waste gas is reduced, and the environmental protection treatment pressure is reduced; the byproduct hydrogen bromide in the reaction proces
