The macroporous ion exchange resin refers to an insoluble infusible polymer having a macroporous structure and a network structure having a functional group. The macroporous resin generally has a pore diameter of 10 nm or more. The surface area is 5m2/g, and the difference between the true density and the apparent density is not less than 0.059/mL resin. The size and shape of the pores do not change with the environmental conditions. In the wet state, the opaque color is milky white, and it is easy to penetrate the solvent and less swell. An ion exchange resin is prepared by adding a porogen during polymerization. If the resin is polymerized with divinylbenzene, styrene and an inert filler calcium carbonate, a macroporous structure can be formed by extracting the filler. Because of its relatively large pore size, porosity and surface area, it can adsorb organic polymer compounds and elute during regeneration. Moreover, it also has good wear resistance and resistance to oxidation and organic pollution, and is used for separation, purification, etc.
