ABSTRACT:
In making polyarylethersulphones or polyaryletherketones or their thioanalogues by reaction of phenols with aromatic halogen compounds, raw polycondensation product is freed of alkali halide by adjusting its composition and/or temperature so that it dissolves at least 0.5% w/w of water and holds the polymer in solution, and then contacting it in liquid form with hot water, preferably under pressure.
