Abstract

The present invention relates to a method of forming a polyarylene ether sulfone polymer by converting a reaction mixture (RG) comprising a dihalogen component (A1), a dihydroxy component (B1) and potassium carbonate (C1) having a volume-average particle size of <25 μm. The present invention further relates to the polyarylene ether sulfone polymers obtainable by said method, to products obtainable from said polyarylene ether sulfone polymer and to membranes formed from said polyarylene ether sulfone polymer.
