A method for preparing a phenolic oligomer antioxidant with a very small residual content of butylated hydroxytoluene (BHT) is provided. Specifically, the method for preparing the phenolic oligomer antioxidant relates to a method which is capable of a BHT-free phenolic oligomer antioxidant or a phenolic oligomer antioxidant containing a trace amount of residual BHT by removing the precursor of BHT as much as possible by performing the concentration under the reduced pressure while injecting an inert gas to an intermediate product and/or removing BHT by performing the concentration under the reduced pressure while injecting an inert gas to the final product.

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 926 m.sup.2/g) combined with strong CO.sub.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.
