Sulfonated resins are applied as catalysts in different reactions such as esterification, etherification, and transesterification. Poly (styrene‐co‐divinylbenzene) particles are the most used material for this kind of application. However, the development of copolymer resins with a longer crosslinker and more flexible chains could improve diffusion, mechanical, and chemical properties allowing the development of customized materials. In the present study, the use of ethylene glycol dimethacrylate, as crosslinker, was assessed in order to find optimal conditions to produce particles with high ion exchange capacity. The experimental study provided sulfonated styrene‐co‐(ethylene glycol dimethacrylate) with ion exchange capacities up to 5.98 meq/g. The present formulations provided resins with similar properties when compared with ion exchange capacity of commercially available products, such as Amberlyst® and Lewatit® resins. Furthermore, the present sulfonation process is energetically attractive because the reactions can be carried out at relatively low temperatures (approximately 58°C) and less reagent amounts in comparison with well‐known synthesis processes.
