    Abstract: The invention relates to a method for purifying a recycling flow (1) from a plant for producing polyarylene ether sulfones by polycondensing aromatic bis-halogen compounds and aromatic bisphenols or salts thereof in the presence of at least one alkali-metal carbonate or hydrogencarbonate or ammonium carbonate or hydrogencarbonate in an N-alkyl-2-pyrrolidone as a solvent, containing 60 to 90 wt% of water, 10 to 40 wt% of N-alkyl-2-pyrrolidone, and, as a specification-impairing contaminant, up to 5000 ppm by weight of the alkyl succinimide corresponding to the N-alkyl-2-pyrrolidone and in addition thereto up to 1000 ppm by weight of additional high boilers in relation to N-alkyl-2-pyrrolidone, in particular inorganic salts, in each case with respect to the total weight of the recycling flow (1), the sum of the components equaling 100 wt%, so as to obtain a pure N-alkyl-2-pyrrolidone flow (2), which can be fed back into the plant for producing polyarylene ether sulfones, by means of purification by distillation in a purification column (K), the method being characterized in that a pre-purification by evaporation in one or more evaporator stages in order to reduce the content of inorganic salts is performed before the purification by distillation, one or more vapor flows (3, 4, 5) being obtained, which are fed to the purification column (K) as feed flows, and the bottom flow from the last evaporator stage being discharged and the bottom flow from the purification column (K) being completely recycled into the last evaporator stage.

    Abstract translation: 用于循环流（1）的纯化方法是通过芳香族bishalogen化合物和芳族双酚类或它们的盐的缩聚中的至少一种碱金属或铵的碳酸盐或碳酸氢盐的N-烷基-2-存在提出了生产聚亚芳基醚砜的植物的 吡咯烷酮作为含有60〜90重量％的水，10至40重量％N-烷基-2-吡咯烷酮和按重量计的N-烷基-2-吡咯烷酮的规范有害污染高达5000ppm的相应的烷基琥珀酰亚胺的溶剂 并偏离高达1000重量ppm进一步高沸点相比N-烷基-2-吡咯烷酮，特别是无机盐，基于在每种情况下对循环流（1）的总重量计，其中，所述组分的总和为100重量％，下 通过在R中纯蒸馏获得可追溯至植物用于制备聚亚芳基醚砜的纯N-烷基-2-吡咯烷酮流（2） einkolonne（K），其特征在于，通过蒸馏纯化是通过在一个或多个蒸发阶段蒸发预清洗之前，以减少无机盐，其特征在于，一个或多个蒸汽流（3，4，5）获得的内容，作为一个进料流 供给纯塔（K），并且其中从最后蒸发器阶段排出的底部物流和来自纯塔（K）的底部物流完全循环到蒸发器的最后阶段。

    Abstract: The present invention relates to a process for the preparation of polysulfones having a yellowness index according to DIN 6167 of less than 19 and polyether sulfones having a yellowness index according to DIN 6167 of less than 30, wherein the polymerization is carried out in basic, aprotic solvents with the use of a positively conveying stirrer passing close to the wall. The present invention also relates to the polyether sulfones and polysulfones obtainable for the first time by this process and to the use of such polymers for the production of moldings, films, membranes and foams.
