Popis: Highly acidic sulfonated polymers are promising heterogeneous catalysts due to their excellent chemical and thermal stability, as well as the possibility of employing low-cost synthesis routes. However, their production is time consuming and control of their chemical and physical properties is often difficult. Here, we produce sulfonated hypercrosslinked polymers using chlorosulfonic acid as a dual polymerisation catalyst and sulfonation agent, consolidating a conventional two-step process into a one-pot reaction. The synthesis time of the networks is reduced from 5-6 days to
