Abstract:
The present invention relates to a method of forming a polyarylene ether sulfone polymer by converting a reaction mixture (R G ) 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.

Claim (Index 25):
A method of reducing the polydispersity (Q) of a polyarylene ether sulfone polymer, the method comprising forming the polyarylene ether sulfone polymer in the presence of potassium carbonate having a volume-weighted average particle size of from 20 nm to 25 \u03bcm,\n wherein: the polydispersity (Q) of the polyarylene ether sulfone is reduced to 4 or less; and Q is defined as the quotient formed by dividing the number average molecular weight (M n ) into the weight average molecular weight (M w ), measured using gel permeation chromatography (GPC), using dimethylacetamide (DMAc) as solvent and narrowly distributed polymethyl methacrylate as standard.
