Установлена взаимосвязь структуры и фазового состояния растворов смесей полифениленсульфона (ПФС) и полисульфона (ПС) и транспортных свойств ультрафильтрационных мембран, полученных на их основе: удельная производительность мембран на основе смесей ПФС и ПС проходит через максимум в области наиболее гетерогенной структуры формовочной композиции при соотношении полимеров в смеси ПФС  :   ПС  = (30–50) : (70–50), и достигает значений 80–87  л ∙ · м–2 ∙ · ч–1, что значительно превосходит характеристики мембран, опубликованные в литературе к настоящему времени.

The correlation between the structure and phase state of the solutions of polyphenylsulfone (PPSU) and polysulfone (PSF) blends and the transport properties of ultrafiltration membranes, prepared from these solutions, is revealed  : pure water flux of the PPSU/PSF blend membranes passes through the maximum at the most heterogeneous structure of polymer solutions at the PPSU  : PSF blend ratio (30–50) : (70–50). In this study, the maximum pure water flux achieves 80–87  l ∙ · m–2 ∙ · h–1, which significantly exceeds the data reported in the literature up-to-date.
