摘要： The present disclosure describes a process for making a hyperporous material for capture and conversion of carbon dioxide. The process comprises the steps a first self-polymerisation of benzyl halides via Friedel-Crafts reaction. In the second step the obtained hypercrosslinked polymer is further coupled with an amine or heterocyclic compound having at least one nitrogen ring atom. The invention also relates to the material obtained to the process and its use in catalytic reactions, for instance the conversion of epoxides to carbonates. Salt-modified porous hypercrosslinked polymers obtained according to the invention show a high BET surface (BET surface area up to 926m 2 /g) combined with strong CO 2 capture capacities (14.5 wt%). The nitrogen compound functionalized hypercrosslinked polymer catalyst shows improved conversion rates compared to known functionalized polystyrene materials and an excellent recyclability. A new type of imidazolium salt modified polymers shows especially high capture and conversion abilities. Carbonates can be produced in high yields according to the inventive used of the obtained polymers.
