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 21):
A mixture, comprising:\n I) a polyarylene ether sulfone polymer comprising in polymerized form:\n (A1) a dihalogen component comprising not less than 50 wt % of at least one dihalogen compound selected from the group consisting of 4,4\u2032-dichlorodiphenyl sulfone and 4,4\u2032-difluorodiphenyl sulfone, based on the overall weight of component (A1), \n (B1) a dihydroxy component comprising not less than 80 wt % of at least one dihydroxy compound selected from the group consisting of] 4,4\u2032-dihydroxy diphenylsulfone, bisphenol A, 4,4\u2032-dihydroxybenzophenone and hydroquinone, based on the overall weight of component (B1), \n and which has a polydispersity (Q) of 3.5 or less, wherein 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; and II) a polyvinylpyrrolidone.
