The internal structure of the resin beads, i.e., whether gel-type or macroporous, is important in the selection of an ion exchanger.
Macroporous weak anion exchange resin, with their high effective surface area, facilitate the ion exchange process. Also, they give access to the exchange sites for larger ions, can be used with almost any solvent, irrespective of whether it is a good solvent for the uncrosslinked polymer, and take up the solvent with little or no change in volume. They make more rigid beads, facilitating ease of removal from the reaction system. 
In the case of the gel-type weak anion exchange resin, since they have no discrete pores, solute ions diffuse through the particle to interact with exchange sites. Despite diffusional limitations on reaction rates, these resins offer certain advantages: they are less fragile, requiring less care in handling, react faster in functionalization and applications reactions, and possess higher loading capacities.
